Chelsea’s nightmare start to the Premier League season could be about to claim another victim after reports emerged on Wednesday that their technical director, Michael Emenalo, is under pressure due to a perceived failure in the transfer market.

The reigning Premier League champions languish in 16th in the Premier League table, with any hopes of retaining their crown won just six months ago all but over after an alarming seven defeats in their first 12 league matches.

With the club’s owner, Roman Abramovich, currently sticking with Mourinho, the axe has fallen on a number of players so far this season, with the likes of John Terry, Nemanja Matic, Eden Hazard and Cesc Fabregas all dropped at some point for poor form.

However, Emenalo is now coming under-fire for a poor string of signings, and The Sun claim that he pay the price should the poor results continue with no signs of any major signings on the horizon in the January transfer window. The former Nigerian footballer, who has a spell with Notts County during his playing career, joined the Blues in 2007 during Avram Grant's reign in charge of the side, before working his way up from chief scout to assistant first team coach following the exit of Ray Wilkins in 2010.In July 2011, he was promoted to his current role of technical director.

Three Chelsea flops were offloaded in the summer, with Filipe Luis returning to Atletico Madrid after an underwhelming season in London, while Mohamed Salah and Juan Cuadrado left on loan to join Italian sides Roma and Juventus respectfully.

Antonio Conte The current Italy manager is Chelsea's preferred target should they dismiss Mourinho, as revealed by the Independent at the start of December.

Pep Guardiola Reports have suggested that the current Bayern Munich manager would be Chelsea's favoured choice to replace Mourinho permanently, but convincing the former Barcelona coach to leave the Allianz Arena midway through the season would appear impossible. However, employing him at the end of the campaign could be a realistic option considering the Spaniard will be out of contract in the summer. Although there are rumours he is on the verge of signing a new deal. AP Who could replace Jose Mourinho as Chelsea manager? Carlo Ancelotti Has already managed Chelsea, during which time he led them to the Double in the 2009/10 season. There are few coaches with such an impressive track-record, but the fact he was shamefully sacked in the tunnel at Goodison Park could make the situation complicated. Would he want to return to a club that treated his with so little respect? The Italian has indicated he would prefer a return to management next season in the Premier League.

Brendan Rodgers His availability makes Rodgers a viable option, although whether the former Liverpool manager matches the calibre of coach that Chelsea would want to employ is debatable.

Also has ties with the club having worked under Mourinho during the Special One's first spell at Chelsea. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? Diego Simeone The Atletico Madrid manager is probably the most exciting option out there. Having led Madrid's second club out of the shadow of Real to the title in 2013/14, the Argentinian proved his combative intense style could yield results. Convincing him to leave his current post could be tricky though, with Simeone agreeing a contract until 2020 earlier this year. Chelsea would have to pay around £15m to Atletico in compensation to buy him out of his contract. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? Ronald Koeman The former Netherlands international has impressed since coming to the Premier League. Having joined Southampton at a time most predicted would be tough for the club after numerous high-profile departures, Koeman led the club to a seventh placed finish thanks to some astute buys and exciting football. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? Laurent Blanc The former France manager could have done little more at PSG since taking over at the mega-rich club, winning the league for the last two-years running and making the French side a force in the Champions League. Among the notable European scalps in recent years was the defeat of Chelsea at the Round of 16 stage in last season's competition, and, providing he stays in Paris, they will meet at the same stage of this year's tournament for the third year running. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? John Terry Captain. Leader. Legend. Manager? Few at Chelsea can claim to command as much respect as their long-term skipper. Whether he would want to step into the manager role is unclear, but as a short-term option until the end of the season, it could be the smoothest transition. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? Gianfranco Zola Zola, who made 312 appearances and scored 80 goals for Chelsea after signing from Parma in 1996, is currently manager of Al Arabi in Qatar. He has signalled his ambition is to one day return to Stamford Bridge as manager. Getty Images Who could replace Jose Mourinho as Chelsea manager? Fabio Capello Former England manager Fabio Capello has been out of work since being dropped by Russia over the summer. He's said is open to taking over at Stamford Bridge, but how well the Italian would be received after his failures with the national team is unclear. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? Guus Hiddink Hiddink had a successful short stint as Chelsea manager in 2009 which saw the club win the FA Cup. The Dutchman was popular among fans and appears a sensible short-term choice.

After overseeing a few poor results after replacing Louis van Gaal, he left his post and the national side failed to qualify for next summer's European Championships. Has been made the bookies' favourite. 2015 Getty Images Who could replace Jose Mourinho as Chelsea manager? David Moyes The former Manchester United manager was sacked by Real Sociedad at the start of November after making a poor start to the La Liga season. Moyes has since appeared on TV and confirmed that he has had numerous offers to return to management in England, and that he is seeking his next job. His availability could make him a possible target through to the end of the season. Getty Images Who could replace Jose Mourinho as Chelsea manager? Juande Ramos The Spaniard will be an unpopular choice after his disastrous spell in charge of Tottenham Hotspur between 2007 and 2008 that lasted just 54 matches. He led Spurs to the League Cup but started the next season with just two points from his first eight matches leading to the appointment of Harry Redknapp. Getty Images Who could replace Jose Mourinho as Chelsea manager? Avram Grant Another former Chelsea interim manager, the Israeli led the Blues to the Champions League final in 2008 after taking over after the first time Mourinho was sacked. Has had spells across Europe since but never replicated that success and was never the most popular figure amongst the Chelsea support.

Added to this is the under-performance of Chelsea’s summer signings this term. Radamel Falcao has made 11 appearances in all competitions yet the Colombian striker has returned just one goal which came back in August, and Mourinho’s decision to put his faith in the former Manchester United striker looks to have been an error.

Left-back Baba Rahmann, who joined the club in a £16m deal from Bundesliga side Augsburg, was singled out for criticism in last weekend’s 1-0 defeat by Stoke, while fellow defender Papy Djilobodji has made just one single appearance this season which came in the Capital One Cup win over Walsall.

After a strong start to life in London having scored on his debut, former Barcelona forward Pedro has struggled for form, having not scored since the Walsall victory in late September, while young Brazilian prospect Kenedy has made six appearance and also found the back of the net against the League One side.

The only success story of the summer has been the signing of goalkeeper Asmir Begovic, although letting Petr Cech join Arsenal – a decision sanctioned by Abramovich himself – could also be seen as an error given his impressive form for the Gunners. Begovic has already played 16 times this season, including 10 of their 12 league games, due to injury to No 1 goalkeeper Thibaut Courtois.
