The summer transfer window might well be shut but that hasn't stopped speculation ahead of the January window.
As things stand, Chelsea's starting central defensive pairing is Gary Cahill and John Terry. Both appear to be in good form as things stand but Mourinho will know that Terry cannot go on forever.
The Chelsea boss has been ruthless cutting club legends like Ashley Cole and Frank Lampard in the past so will likely have no problems getting rid of the veteran central defender when the time comes.
Chelsea have been linked with a swoop for Real Madrid defender Raphael Varane for some time now, but Carlo Ancelotti says he's going nowhere.
The young French centre-back was given his chance to shine in the Real Madrid first team by Mourinho before left to take over at Chelsea, and apparently the pair share a good relationship.However Ancelotti says he intends on keeping the youngster, and won't be selling him at any price despite the fact that he's behind both Sergio Ramos and Pepe in the Madrid pecking order.
When quizzed about Varane's future, he said: "He is a Real Madrid player, he is young and we need him. If he is going through a difficult time, we will help him. I always say that we have Ramos and Pepe, who are two of the best defenders in the world."
The Blues have more pressing matter than the transfer window for the time being, namely getting their Champions League campaign up and running with a win. They take on Schalke at Stamford Bridge this evening.
Didier Drogba looked to be a doubt for the clash against the German outfit but he trained with his team-mates ahead of the game yesterday.
Best in the world
Finally, Jose Mourinho says Eden Hazard has the ability to become one of the best players in the world. The Belgian is expected to put pen to paper on a huge new £200,000-per-week five year sea in the near future.
He has three years remaining on his contract with Chelsea, but Mourinho has acted quickly to keep him from the clutches of PSG and Real Madrid.
