Will Chelsea manager Jose Mourinho win the title in his first season back at Stamford Bridge?
That's the question on everyone's lips at the west London clubs right now - and it's certainly a possibility, even after last night's frustrating 0-0 draw with West Ham.
But who are the best five players in Chelsea's current squad?
And would Juan Mata have made the cut had Mourinho not sold him to Manchester United for £37.1m earlier this month?
5. David Luiz
Some love his playing style, others are less than convinced, but there's no doubt that David Luiz is a high-quality player.
His versatility makes him an invaluable player for Chelsea: he can play as a centre-back, a defensive midfielder or even in central midfield.
That flexibility is a reason why the likes of Barcelona and Bayern Munich are keen to sign him.
And let's face it: you can't be that bad a player if Pep Guardiola wants to sign you.
4. John Terry
John Terry is currently enjoying an Indian summer in his career, and the former England captain has reminded everyone just how good he is over the course of this season.
The centre-back hasn't missed one Premier League match so far this term, which has led to many calls for him to be included in the England squad for this summer's World Cup finals in Brazil.
3. Petr Cech
Petr Cech makes it to number three on this list but, bizarrely, he's not even the best goalkeeper on Chelsea's books.
Thibaut Courtois is arguably the second-best goalkeeper in Europe behind Manuel Neuer right now, yet the Atletico Madrid 'keeper hasn't played a single minute for parent club Chelsea.
That's because Cech, for the time being, remains a hugely reliable and consistent goalkeeper.
The reason Juan Mata eventually wanted to leave Stamford Bridge - and why Jose Mourinho was prepared to let him leave - was because of Oscar.
The Brazil international is now one of Chelsea's key players - and, at the age of 22, he will just keep getting better and better.
1. Eden Hazard
But sitting top of the pile is Eden Hazard, who has come on leaps and bounds this season.
The Belgian winger is capable of producing breathtaking moments of quality; and you suspect that he is one of a few current Premier League stars capable of winning a Ballon d'Or at some point in his career.
The 23-year-old is still some way off the level of Lionel Messi and Cristiano Ronaldo, but his potential is frightening.
