So after some very busy weeks of football we take a look at how Chelsea's team have performed and weather or not they should sign any new players in the January transfer window.
With Chelsea currently sitting 4th in the League it's obvious they haven't performed as well as there fans would have liked them too.
Losing points when they should have gained points is not a good thing in one of the most competitive leagues in the world and with it looking like any of the top teams could win, accumulating points is vital.
Chelsea's defence looking solid so far this season having only lost 2 of there 11 games - but they have conceded 10 goals so they could look to bring in a new defensive player.
Mourinho has already looked at bringing in a new defensive player last summer having looked at Eliaquim Mangala, a bright young CB from FC Porto, who looks like he could be one of the future's best centre-backs.
But with Chelsea's rival Manchester United also interested in Mangala's services and FC Porto wanting €37 million for the player, the Blues could have a problem in getting the young defender.
There is also the problem of Ashley Cole not getting any younger and Bertrand being good but there are doubts over whether he can make the grade.
Chelsea could look to be in the market for a new left-back.
They could look to bring in Luke Shaw, who is looking like one of the best young stars and could be very likely be one of the best left-back's in the world.
But with Manchester United interested in signing the promising player it might be much harder.
Nobody can say that Chelsea don't have one of the best midfields in the world with the likes of Mata, Willian, Schurrle, Oscar, Hazard and Kevin De Bruyne.
But their defensive midfielders are looking worse for wear and Mourinho could look to bring in some fresh blood.
Ramires has been playing great, but Lampard doesn't suit his new defensive role and is a liability at that position.
Mikel has played decently when he has been called upon but Mourinho doesn't look like he's planing on playing the Nigerian very much any time soon.
Jose was reported to be looking at Xabi Alonso and De Rossi but with those two both getting older by the second he could be in the market for a younger player. With Matuidi's contract talks with PSG going nowhere Chelsea could try and sign him.
Last but not least is Chelsea strike force. Chelsea recently brought in Eto'o a striker from Cameroon.
Eto'o hasn't played the best but has given Chelsea some much needed goals. Then there's Torres, he has scored four goals this season - one of which gave Chelsea the late win against Manchester City.
Torres seems to play amazingly in European matches but isn't the best in the BPL and Chelsea could have better.
Demba Ba isn't starting very much and only has one goal so far which is good since he has only been started in three games.
Chelsea could bring in a striker in January. With Costa, Falcao, Lewandoski and Jackson Martinez being linked with Chelsea - all but Lewandoski seem pretty realistic. They're all great players and anyone of them could be brilliant at Chelsea.
