In football, there is no guarantee how long a manager is going to last in a job, with Chelsea the epitome of this.
Since the arrival of Russian billionaire Roman Abramovich in 2003, the Blues have gone through no less than ten managers since.
Currently, Jose Mourinho is the man in charge of Chelsea. Last season, the Portuguese manager led the London based side to the double, winning the Capital One Cup and the Premier League title, and has recently signed a new four-year deal to remain at Stamford Bridge until 2019.

But a question that is often asked is: Who will replace Jose Mourinho as Chelsea manager? Here, we take a look at five managers who could take the reigns at Chelsea in the future.
5. Pep Guardiola
Spaniard Guardiola is one of the best managers in the world, and Chelsea wouldn't think twice about approaching him as manager.

At Barcelona, Guardiola won everything and anything, while building his own form of football - 'Tika Taka'. Similarly, while under the helm at German giants Bayern Munich, he has led the club to numerous titles and cup competitions.
Before Mourinho began his second tenure in 2013, Guardiola's name was heavily linked with the Chelsea managerial position but instead chose Bayern, though there is little doubt that he would jump at the chance to manager in England in the future.
4. Carlo Ancelotti
Although Ancelotti was sacked by Chelsea in 2012, few would doubt that the Italian could make a return to Chelsea's dug out.
Whilst at Chelsea, Ancelotti led the side to a double in his first season in charge of the club. His second season didn’t eclipse the first, though, and he was given the sack by Abramovich.
Following his stint at Chelsea, the Italian manager has gone on to lead Paris Saint-Germain to Ligue 1 titles and even won La Decima with Real Madrid before being sacked in 2015.
3. Jurgen Klopp
Klopp will be one of the first names that Chelsea would consider as a future manager.
At Borussia Dortmund, the German led the side to back-to-back titles and led them to a Champions League final, losing 2-1 to rivals Bayern. He was undoubtedly a fan favourite at the club, and many were shocked to see his departure at the end of the 2014/15 season.
Klopp is currently without a club and has been linked with numerous jobs since he left Dortmund. Given his managerial CV, it comes as no surprise.
2. Diego Simeone
Atletico Madrid manager Simeone would be one of the bookies’ favourites to take over at Chelsea as of when the job becomes available.
Simeone is no stranger to success. During the 2013/14 season, to the surprise of many, he led Atletico to the La Liga title, beating both Barcelona and city rivals Real Madrid to the trophy.
In the same season, the Argentine led Atletico to a Champions League final against their Madrid rivals. They were within minutes of lifting the trophy, but a late equaliser forced extra time and Real went on to win their tenth Champions League title - La Decima.
If he did take the Chelsea job, he would reunite with many players he coached at Atletico, including Diego Costa and Thibaut Courtois.
1. John Terry
Current Chelsea captain Terry will become a future manager of Chelsea, it's written in the stars.
The 34-year-old has led the club to countless trophies, including four Premier League titles, a Champions League title, numerous FA Cups, and many, many more.
The centre-back knows the club inside out and his passion and desire for the team will put him in could stead for a future managerial position.
