Bolton Wanderers defender Gary Cahill insists they can shock Chelsea today at Stamford Bridge.
Cahill said: "It has been a very tense six months, but we will be a lot more relaxed than in recent games. And players can do things more naturally when they are relaxed.
"Chelsea haven't lost at home for years and that takes the pressure off us even more. Sooner or later that run will be broken and it could be us. Nobody expects that but sometimes being underdogs does you a favour. We tend to do well against big sides, we raise our game. We beat United earlier in the season which was a massive result for us."
