Harry Redknapp's position at Queens Park Rangers is under increasing threat, with the club’s hierarchy considering replacing him with former Tottenham manager Tim Sherwood.

Redknapp is not in immediate danger of losing his job but relations between him and the board have become strained in recent weeks following a poor start to the season which has left QPR bottom of the Premier League table with one win from seven matches.

Talks had begun over a new contract several months ago but Redknapp’s unwillingness to commit - a stance he declared publicly last week - combined with QPR’s abject displays have prompted chairman Tony Fernandes to ponder alternatives.

Fernandes remains an admirer of Redknapp but the lack of spirit in many of QPR’s performances this season have led to suggestions internally that the club may soon need to make a change.

For now, Fernandes is supportive of Redknapp yet mindful of how long the club waited before sacking Mark Hughes in 2012 - 12 games into the campaign. His resolve could be tested further with matches to come against Liverpool, Aston Villa, Chelsea and Manchester City.

How QPR’s summer signings have fared so far 10 show all How QPR’s summer signings have fared so far 1/10 Rio Ferdinand: D Complained that Manchester United let him leave too early, but has not proved much of a point so far. Looks a shadow of the player he once was, and the 36-year-old needs to raise his game for QPR to get out of trouble. 2/10 Steven Caulker: C Hailed as one of Redknapp's coups of the window, the £8m signing from Cardiff is, at this rate, on course to suffer his second relegation in a row. Has not formed the strong partnership with Ferdinand as expected (although has not been helped by distractions off the field when he was wrongly arrested for nicking some cream cheese from a supermarket). 3/10 Jordon Mutch: C Started his QPR career fairly brightly after joining from Cardiff for £6m and looked like he would add some vibrancy to the midfield and in attack. However, a nagging hamstring injury has seen him more on the sidelines than on the pitch of late and his presence has been sorely missed. GETTY 4/10 Mauricio Isla: D It's always a bit more of gamble to bring in a player from overseas, especially when Rangers already had a reasonable right back in Danny Simpson. The latter was surprisingly sold to Leicester City to make room for the Chile international, who joined from Juventus on loan in view of a permanent move, and it has not looked the right decision so far. Isla has struggled to adapt to the English game, is being beaten by wingers far too easily and needs to raise his game. GETTY 5/10 Leroy Fer: B One of Redknapp's more astute acquisitions. After an impressive debut season with Norwich in the Premier League, albeit in a losing cause, Fer moved to west London for £8m, and there have been enough signs of intent for Rangers fans to like what they see from the midfielder. Nicknamed 'the bouncer' he has been building up to full match fitness after going away with Holland at the World Cup and will surely improve as the months go by. GETTY 6/10 Eduardo Vargas: D Another Chile international acquired on loan, and another yet to make a positive impression. Has the build and size of Alexis Sanchez, but shown little of the attacking threat. Vargas has yet to find the net so far, which is one of the reasons why QPR have a measly four League goals to their name. Redknapp seems unconvinced too having handed him just two starts since his switch from Napoli and to make matters worse, he passed up on the opportunity to sign West Ham's prolific forward Diafra Sakho. GETTY 7/10 Jack Robinson: C Bought as one for the future, the left back was sent to Huddersfield on loan immediately after his £1m switch from Liverpool. Appeared to initially find tough in a struggling side, but is starting to find his feet under new manager Chris Powell. Given the latter's vast experience at playing as a left in his professional career, perhaps it's no surprise the England Under-21 international is looking better under his stewardship. Getting the chance to work with Powell is an added bonus for QPR and his development. Getty 8/10 Alex McCarthy: E Not done anything wrong, well, apart from perhaps joining QPR in the first place. It always looked a strange decision from the 24-year-old keeper to move to Loftus Road with Rob Green still firmly installed as No1. McCarthy, who turned down a late offer from Liverpool to be back up to Simon Mignolet, chose QPR because he thought there was a better chance of first team football. Two months later and he's not played a single minute. Mccarthy signed a four-year deal so will hope more opportunities arise in the future, yet it seems a waste to see a talented keeper just warming the bench. Getty 9/10 Sandro: D There was a huge outcry from Tottenham fans when they cashed in on the Brazilian in a deal worth up to £10m, but the club's owners may have the last laugh. A quality player when 100 per cent fit, the only problem is he looks half that so far. Not been quite the same player since suffering a knee ligament injury for spurs against QPR last January and Redknapp admits he's not fully fit now. A very likeable character and just what QPR need to get out of trouble, but not in his current state. Getty 10/10 Niko Kranjcar: B Probably the best signing of the lot. The prospect of re-signing him on loan from Dynamo Kiev after an underwhelming spell in the Championship last term didn't excite Rangers fans. But he has returned much fitter and with more of an appetite for the game. The fact he took a sizeable pay cut to return shows his heart is in the right place and he has been one of QPR's more creative players. A silky touch compensates for a lack of speed and is a real threat from set pieces as his stunning equaliser against Stoke showed.

Sherwood’s name has been raised by club officials and it is believed the former midfielder is keen to return to work after his five-month spell in charge at White Hart Lane.

Les Ferdinand was Sherwood’s assistant during his time at Spurs and is now QPR’s head of football operations. Sherwood had chances to return to the game after he left Spurs but could not reach an agreement with West Brom or Crystal Palace.

Despite his unpopularity among a section of Spurs fans, Sherwood left the club with a win percentage of 59 per cent in the Premier League, the best of any boss at White Hart Lane since 1992.

No decision has yet been taken on Redknapp, whose contract expires at the end of the season, but a marked improvement in performance is required to avoid further pressure on Fernandes to act.
