Chelsea captain John Terry is expecting a tough test against Tottenham Hotspur on Sunday.
Spurs travel to Stamford Bridge for the London derby and Terry admits that he has been impressed with Harry Redknapp’s side.
Terry said: “They’ve started very well and Harry made some great signings in the summer.
“Jermain Defoe is on fire, Peter Crouch is difficult to play against and Aaron Lennon played well for England.
“They’re a good side and especially if they keep Ledley King fit because he makes them a lot stronger at the back.”
