The Blues have shipped some goals lately and have made some costly mistakes at the back as well and are in danger of seeing their chances at both the English Premier League title as well as a chance at the UEFA Champions League title go up in smoke within the next week if they fail to defeat Stoke.
Ramires still has time to serve on his suspension while Samuel Eto'o and Ashley Cole are still out injured.
The Potters are on a roll and have taken 13 points from their last 15 and Mark Hughes has his full slate of players to choose from save for Liverpool loaner Oussama Assaidi whom is doubtful as Robert Huth remains out injured.
If there is a side that has the ability to be physical and miraculously break Mourinho's home unbeaten streak it truly could be Hughes' physical Stoke side.
Chelsea XI: Cech: Ivanovic, Cahill, Terry, Azpilicueta; Matic, Lampard; Schurrle, Oscar, Hazard; Torres.
Stoke XI: Begovic: Cameron, Shawcross, Wilson, Pieters; N'Zonzi, Whelan; Odemwingie, Ireland, Arnautovic; Crouch.
