Jose Mourinho has returned to Chelsea, but what's different? Here are five things we have learned about them this season.
1) Best squad in the world? - There is definitely no other Premier League side that could boast this, but perhaps Chelsea can.
A team packed to the brim of Chelsea's youth team is currently table topping the Dutch Eredivisie, looking down the likes of Ajax, Twente and Feynoord. Everton have also turned themselves into a viable top 4 side, due to a Chelsea loanee - so it seems that other clubs are making the most of their strength in depth.
Whilst their strongest 11 may not be the best in the world, their strength in depth is, for me, is undeniable and holds it's own with anyclub in world football.
2) The happy one? - Infamously Jose Mourinho proclaimed on his return to Stamford Bridge that he was the 'happy one', alas that is no longer the truth.
It's fair to say Chelsea HAVE had a good season so far, but it has been undone by a few slip-ups in the league. A draw against West Bromwich and losses to Stoke and Newcastle United are the stand-out results, which have left the Portuguese manager pulling his hair out.
In the last loss to Stoke, he wrote his sides title chances off. I think he may have had a wobbly bottom lip, they're well placed for the title race.
Chelsea have seen just 3 league goals come from their 2 front men, and buying a striker in January has been voiced by fans as their main priority. Mourinho has consistently said he will work with what he has and won't worry about other sides players, and despite having one of the countries leading goalscorers on his books (albeit at another club) he hasn't admitted regret over the current set-up.
I think Chelsea could well need a proper number 9 in the transfer window, someone that can push them over the line and win the title. It's not like they're lacking the funds to go out and make a 'statement' signing, hopefully this time he will turn out to be better than Torres.
4) Count on the old guard - The past few years have seen the 'old guard' written off by the press and other fans, yet they're constantly at the core of success Chelsea have and this season has been no different.
Ashley Cole may have found it difficult this season with the form of Cesar Azpilicueta but John Terry and Frank Lampard have been going from strength to strength, perhaps not at the same level they once were - but, certainly not done and dusted.
John Terry is without question England's best centre back, even at his grand old age of 33 and if it wasn't for poor treatment then our national side would be much better going into Brazil in the summer.
Lampard has appeared in all 15 games, with 11 of them starting in the first XI. He has managed 4 goals and 3 assists and can only be bettered by Eden Hazard when it comes to attacking productivity - outstanding really, and perhaps even now.. he is England's best midfielder.
5) Deadly duo - Chelsea have some of the most exciting attacking midfielders in world football, with the likes of Mata, Schurrle, Willlain and Kevin De Bruyne. For me though, there is two that stand above all of them and that is Belgium's Eden Hazard and Brazil's Oscar.
Hazard has provided a cutting edge for Chelsea this season, with his undeniable ability to get past his man and offer goal-scoring opportunties, it makes you wonder what a half decent striker could make of his service.
And then there is Oscar, tipped by many to fill the void that will inevitably left by Frank Lampard leaving. The Brazilian has 5 goals already this season, and will be hungry for a strong finish to the season - to hopefully cement his place in the Brazil XI when the world cup hits. He has the world at his feet, no doubt about that.
