After it was confirmed last week that Jose Mourinho would be leaving Real Madrid by mutual consent at the end of the season it just increased the speculation that he would be returning to Chelsea for his second tenure at the club where he enjoyed great success.
However, Mourinho will have to make some crucial changes to a huge squad with a number of quality young players on loan and the ability to spend big.
Here are five problems that the controversial character may face.
1. The goalkeeper situation
Chelsea have two of the best keepers in the world in Petr Cech and Thibaut Courtious and neither of them will be content with a spot on the bench.
Mourinho will know all about the talents of Courtouis after his heroics in the Copa del Rey final and consistent performances throughout the Liga season, staking his claim as arguably the best young keeper in the world.
Nevertheless, Cech is a world-class 'keeper and has been in fine form in recent years, from his heroics in the Champions League last season to his consistent performances this season.
Mourinho faces a tough task on whether to keep the man who was in goal during his last spell at the club and to send the young Belgian on loan again - or could it be time for the youngster to step up and represent his parent club on a weekly basis?
2. The loanees
Chelsea have a remarkable amount of quality young players on loan across Europe this season.
At home in England, Chelsea have a few players who have impressed, especially the big striker who many are dubbing “the next Didier Drogba” - Romelu Lukaku.
The young Belgian has been on fire at West Brom this season, scoring 17 goals in the Premier League. Also, the 18-year-old England International Nathaniel Chalobah has been in great form at Watford this season helping them to a place in the play-off final.
Josh McEachran is another who has been at Championship side Middlesbrough and is still only 20 years of age. Across Europe, Chelsea have more loanees such as 21-year-old Kevin De Bruyne, who has been one of Werder Bremen’s best players this season; Lucas Piazon, who has been at Malaga since January, and Patrick Van Aanholt who has been impressive this season for Vitesse.
Another man that Mourinho rates highly and knows so well is Michael Essien. The versatile Ghanian is a favourite of Mourinho and will be surely be returning from Real Madrid in the summer.
With all these quality players on loan the special one faces some crucial decisions on who to bring back to the first team and who to leave out on loan for more time to develop their skills.
3. The striker dilemma
Since the loss of Didier Drogba at the end of last season, Chelsea have trusted in the £50m man Fernando Torres to deliver the goals.
The signing of Demba Ba in January may have eased the pressure on Torres but the pair have not been providing the goals in the Premier League.
Although Torres has had an improvement on last season, scoring 21 times for the Blues this time around, many believe Chelsea are still lacking that clinical striker up top.
Chelsea could recall Lukaku, who has scored 17 times in the Premier League this season for West Brom - a record for the club. However, Chelsea could look to splash the cash on a big player this summer after being linked with Robert Lewandowski, Edison Cavani and Radamel Falcao, all whom have been in fantastic form this season.
It is one of the most talked about problems at the London club and Mourinho faces a hard decision on what to do.
4. The summer signings
This summer is shaping up to be one of the most interesting transfer windows in footballing history, with many clubs under new management looking to rebuild for the following season.
Chelsea are one of those clubs and will certainly be looking to improve on their squad. Mourinho faces the tough task of deciding which positions need strengthening and who to sign to fill those positions, such as the striker and defensive midfielder roles which many believe the two aspects of Chelsea’s team that could do with more quality.
5. His relationship with Roman Abramovich
It is no secret that last time Mourinho was at Chelsea he had a number of problems with Russian owner Roman Ambramovich.
From his decisions on signing players to his team selection, tension rose between the two on a number of occasions and it was eventually the reason the 'Special One' left the club.
This time around it is important that both see eye to eye to ensure that things run smoothly at the club. It’s one of the crucial factors that Mourinho will encounter if he returns as a good relationship with the owner is always a good thing to have.
