Despite winning their last couple of Premier League games many claim Chelsea have dropped in form. West Brom will hope to take advantage of this.
Saido Berahino has been in exceptional form and will be providing a worry for Chelsea's back line and with the return of Craig Gardener, Alan Irvine could cause a big upset at the Bridge.
However, sides managed by Mourinho are known for conceding a small amount of goals and Chelsea are yet to lose this season. The fact that Costa and Fabgregas will most likely be available for the game will provide a concern for Alan Irvine.
With Mourinho's recent comments questioning the noise of the Stamford Bridge faithful the match will likely be a lively occasion for Chelsea fans and West Brom fans alike after Irvine has managed to get the Baggies to 13th.
All the players will be invigorated by the crowd and the match should be a thrilling one.
