Rafael Benitez has said that he is expecting a difficult game when Chelsea head to Wembley for their FA Cup semi-final this weekend.
The current cup holders face Manchester City in the last four of the competition on Sunday.
Chelsea's interim manager told the club's website: "Man City are in a good position in the table and they did well against Man United the other day so we know it will be difficult.
"It is a semi-final and a massive competition and we know what we did wrong when we played against them. We will try to do these things well on Sunday.
"The squad are doing really well. They are working very hard and I can change players and still keep a good level, so I am really pleased with that."
The match comes just three days after a trip to Russia in the Europa League for the Stamford Bridge side.
