Jose Mourinho's second reign at Chelsea may be in its final days. The Portuguese manager has seen his side fall from the heights of winning the league in May and currently lie in 15th place, nine points behind the Champions League spots.
Chelsea have lost half of their league games this season, with two of those losses coming at home. It's the first time that Chelsea have ever lost two home league games in a season under Mourinho in either of his spells.
Who could take over from the 52 year old should he leave the Londoners for a second time?
Guus Hiddink
The Dutch manager could be a sensible short term appointment for Chelsea if they are looking for another target in the summer. Hiddink is currently out of a job after leaving the Netherlands earlier this year when they were struggling to qualify for Euro 2016. The 68 year old managed Chelsea in the first half of 2009 after Luis Felipe Scolari was sacked and won the FA Cup. He has a relationship with Roman Abramovich from his time in charge of Russia.

Carlo Ancelotti
The Italian has previously been in charge at Chelsea and led the team to a title in 2010 after succeeding Hiddink in 2009. He only lasted two seasons in the job before being sacked in the bowels of Goodison Park after his second season at the club was trophyless. Ancelotti's stock rose even further after leading to Real Madrid to their tenth Champions League title. He is currently without a club after leaving Madrid last summer.
Diego Simeone
The Atletico Madrid manager has shown how shrewd a manager he is in La Liga leading Madrid's second team to La Liga and Copa del Rey titles in recent years. Simeone has also proven his worth in European football winning a Europa League and reaching a Champions League final. Two of the stars of his league winning Atletico team are now at Chelsea in the form of Thibaut Courtois and Diego Costa. Would Cholo fancy an opportunity to rejoin his former stars?
Pep Guardiola
The manager that all the clubs would love to have! Guardiola is currently in charge of Bayern Munich and already looks on course to win the Bundesliga title for the third season in a row. The 44 year old's contract with the German champions finishes at the end of the season and despite Bayern's confidence in Guardiola staying in Germany, he has yet to sign a new deal. Manchester City have been consistently linked with Guardiola, but Chelsea may try and swoop in.
Fabio Capello
Capello may be best remembered in England for his disappointing spell in charge of the national team, but he has proven his worth at club level. The Italian has won league titles in Italy and Spain and has also won the Champions League with AC Milan. The 69 year old may fancy one final spell with a top European team and is currently out of a job after leaving the Russian national team earlier this year.
