Jürgen Klopp has ruled striker Daniel Sturridge out of Liverpool's Premier League trip to Leicester next week having already revealed that he will not feature in this weekend’s FA Cup fourth round tie against West Ham, and admitted that he doesn’t know when the England international will play again.

Sturridge has not played since the 2-0 defeat by Newcastle at the start of December, and he has started just four matches this season after struggling with calf and thigh injuries.

Last week, Klopp said that Sturridge would miss the Premier League trip to Norwich – a game that ended in dramatic fashion as Adam Lallana secured a 5-4 victory at Carrow Road – as well as the mid-week encounter with Stoke that saw a penalty shootout wins send the Reds to Wembley where they will face Manchester City in the Capital One Cup final.

But speaking in a press conference ahead of the FA Cup visit of West Ham this Saturday, Klopp said when asked about Sturridge’s condition: "No news. He’s still working. He has done lot of sessions in last week's. It always interrupted.

“Sometimes it’s better, sometimes it’s worse,” Klopp added. “That's normal with (his) injury history. We have to be really sensitive. That's how it is.

"I think everyone in this room knows Daniel better than me. There is no doubt about quality. He's a very good player but he's not available. Not available for tomorrow or Leicester. Don't know what happens after Leicester.”

Liverpool: Players linked with transfers Show all 28 1 /28 Liverpool: Players linked with transfers Liverpool: Players linked with transfers <b>INS: </b>Mattia Perin (Genoa) Regular poor performances from Simon Mignolet have meant speculation speculation surrounding the goalkeeper position has been rife. Perin, 23, is seen as a future replacement for Gianlugi Buffon but he is being linked as a potential replacement for Liverpool understudy Adam Bogdan. Getty Images Liverpool: Players linked with transfers Alex Teixeira (Shakhtar) Liverpool showed their hand on 21 January when they made an audacious £24.6m offer to sign Shakhtar Donetsk forward Alex Teixeira, who has been linked with a move to Premier League rivals Chelsea. Is said to have already agreed personal terms but the Ukrainian club, who were in Orlando for the Florida Cup at the time, reportedly value the 26-year-old at £38m. Getty Liverpool: Players linked with transfers Marc-Andre ter Stegen (Barcelona) Is the clear No 2 at Barcelona to Claudio Bravo but the German is an extremely talented keeper and also nine years younger than the Chilean. Klopp has already said "no", Simon Mignolet has signed a new five-year deal, but the rumours just won't go away. Getty Images Liverpool: Players linked with transfers Robert Lewandowski (Bayern Munich) No chance. At all. The reasons he might: He used to play for Klopp. The reasons he won't: Klopp couldn't hold onto him at Dortmund; he's valued at £70m; he said he doesn't want to play in the Premier League; Real Madrid are of much more interest to him; Liverpool are not Champions League or title contenders; why would he leave Bayern Munich unless for a team on par or better? Sorry. Liverpool: Players linked with transfers Alvaro Morata (Juventus) A new name to be linked with the club, Gazzetta dello Sport report that Liverpool are battling Manchester United and Arsenal for the Spaniard, who starred in last season's run to the Champions League final. He is out of favour this season however and has just one Serie A goal - Juventus are still said to want £45m for the 23-year-old. Liverpool: Players linked with transfers Javier Hernandez (Bayer Leverkusen) The Reds are linked with a summer move for former Manchester United striker Chicharito, who has been in unstoppable form for Leverkusen this season. Liverpool: Players linked with transfers Granit Xhaka (Borussia Monchengladbach) The 23-year-old Swiss midfield enforcer is an impressive athlete and good on the ball. Borussia Monchengladbach are said to have put his asking price at around £20m and will listen to offers. He has said it is "a childhood dream" to play in the Premier League. Liverpool: Players linked with transfers Mario Gotze (Bayern Munich) Unlikely but, having struggled with injury recently, the World Cup winner has been linked with a Jurgen Klopp reunion. Getty Images Liverpool: Players linked with transfers Andrea Ranocchia (Inter) The defender has fallen out-of-favour with boss Roberto Macini, despite captaining the side last season. Ranocchia, who has rejected a move to Norwich City, could be available on loan. Getty Images Liverpool: Players linked with transfers Neven Subotic (Borussia Dortmund) A Klopp favourite during his time at Dortmund. Could provide more cover at centre-back that the Liverpool boss needs. Getty Images Liverpool: Players linked with transfers Joel Matip (Schalke 04) The defender's contract runs out in the summer and Liverpool have agreed a deal in principle to bring him to Anfield on 1 July. 2015 Getty Images Liverpool: Players linked with transfers Marco Reus (Borussia Dortmund) Seizing the signature of Borussia Dortmund’s mercurial winger has been a pipe-dream for many a Liverpudlian over the last three years - but now that his mentor has arrived at Anfield, what was once improbable is now very slightly possible. Has apparently made a pact with Pierre-Emerick Aubameyang not to leave until the other is ready. Getty Images Liverpool: Players linked with transfers Domenico Berardi (Juventus) The Italian has drawn comparisons with Thomas Muller during his spell on loan at Sassuolo from Juventus. He is a good finisher who can play on the wing, at number 10, and also up front- at the ripe age of 21 he has 33 Serie A goals to his name and would offer Liverpool a refreshing level of versatility. However, it is hard to say whether Juventus would be willing to let him go or not. Getty Images Liverpool: Players linked with transfers Diego Lopez (AC Milan) A potential goalkeeper solution could see Liverpool look to offload Mario Balotelli, who is already on loan at the San Siro, in exchange for Spanish stopper Diego Lopez. Lopez, who won the Champions League with Real Madrid in 2014, is 34 and has a few years left in him. Due to recent injury his position has been taken by the exceptionally talented 16-year-old Gianluigi Donnarumma. Getty Images Liverpool: Players linked with transfers Jack Butland (Stoke City) The young Stoke keeper has enjoyed a marvellous season so far - he’s made the third most saves in the Premier League this season and a lot of them have been spectacular. His quality belies his youth but Simon Mignolet recently signed a new five-year deal. Getty Images Liverpool: Players linked with transfers Riccardo Saponara (Empoli) The Italian is another pacey attacking midfielder who can play centrally or on the wing. He struggled in a brief spell at AC Milan but at Empoli he has been brilliant, with 11 goals and seven assists in 26 matches since re-joining the club in January. He's rated at €20m. Getty Images Liverpool: Players linked with transfers Jese Rodriguez (Real Madrid) The Real Madrid man has seemingly been linked with a move to the Reds forever. But now that he is playing more regularly at Real Madrid, there seems to be less noise concerning an exit from the Bernabeu. Getty Images Liverpool: Players linked with transfers Lucas Biglia (Lazio) The Lazio and Argentina hard man has previously been linked with the club and rivals Manchester United. He's already 29 and plays in the same position as the younger Lucas Leiva, who has impressed under Klopp after falling out of favour with Brendan Rodgers. Seems unlikely. Getty Images Liverpool: Players linked with transfers Mauro Icardi (Internazionale) The Italian striker is now one of Liverpool's 'top targets' according to reports in Italy. He would cost €35m (£24.5m) to bring to the club from Inter, where he has eight goals in 16 league matches this season. He was joint top scorer in Serie A last season with 22. But with big money strikers Sturridge and Benteke already at the club, does Klopp really need another? Getty Images Liverpool: Players linked with transfers Leroy Sane (Schalke) German newspaper Bild has the Reds linked with Schalke's teenage winger. The 19 year old is already a German international and Bild claims that Klopp has launched a £10m bid. 2015 Getty Images Liverpool: Players linked with transfers Rico Henry (Walsall) The Walsall teenager has been dubbed the new Ashley Cole and is apparently being chased by all the big boys. The left-back, who can also play as a midfielder, has been watched by scouts of Liverpool, Tottenham, Manchester City and Arsenal. Getty Images Liverpool: Players linked with transfers Shane Long (Southampton) Shane Long has been linked with a move to Anfield following the arrival of Charlie Austin at Southampton. Apparently Saints could be open to letting the Republic of Ireland international depart for around £8m now that cover has been found. GETTY IMAGES Liverpool: Players linked with transfers Mario Lanzini (West Ham United) The transfer committee obviously still like signing players who have performed well against them. The Italian is on a season-long loan from Al Jazira so any move would have to wait for the summer. Lanzini has a £5.5m buyout clause. Getty Images Liverpool: Players linked with transfers <b>OUTS: </b>Jose Enrique (defender) Last played in January after being frozen out by Rodgers, Klopp has given him another chance to make an impression. He almost joined West Brom on deadline day and may well be of interest to Premier League clubs again in January. Getty Images Liverpool: Players linked with transfers Daniel Sturridge (striker) The oft-injured striker is linked with a cheeky £18m bid by West Ham United. It seems unlikely but Sturridge has played just six matches this season and it is not known if he has the full trust of Jurgen Klopp Liverpool: Players linked with transfers Joe Allen (midfielder) Forever linked with the exit door, the Welshman is always mooted for a move to another Premier League club. That hasn't change this month, with former club Swansea interested. Getty Images Liverpool: Players linked with transfers Divock Origi (striker) The Belgian youngster started a couple of games but proved he was a long way away from being ready for Premier League football. Another loan spell could beckon despite Liverpool's striker crisis. Getty Images Liverpool: Players linked with transfers Christian Benteke (striker) Joined the Reds from Aston Villa for £32.5m in the summer but is already said to be disgruntled at his lack of playing time under Jurgen Klopp. The Belgian has only started three matches in 2016 with the German preferring Roberto Firmino - of those three starts, two came against Exeter City in the FA Cup. Will apparently consider his options after Euro 2016

Klopp also revealed that captain Jordan Henderson will not feature against the Hammers as he is still struggling to recover fully from the ankle injury that has hampered his season, having been replaced short of the hour mark during the win over Stoke.

"He did really well for the team,” Klopp said. “[It’s a] Long-term injury and still having pain."

Jordan Henderson has been ruled out of the FA Cup clash with West Ham (2016 Liverpool FC)

There was good news elsewhere though, with Dejan Lovren back in contention and Steven Caulker available to boost Klopp’s defensive options. Right-back Nathanial Clyne will face a late fitness test before a decision is made on his participation, and while influential midfielder Philippe Coutinho remains out injured Klopp was happy to reveal that he is nearing a return from the hamstring injury he suffered at the start of the year.

He confirmed: "Lovren is back, Caulker is available. Coutinho is close to returning to fitness, still doing rehab. Clyne is possible. Much better."

The German admitted that he is not close to signing any new players ahead of Monday’s transfer window deadline, and stressed that he will not look to buy his way out of the injury crisis that has blighted his start to life at Anfield.
