He told the London Evening Standard: "Cech is still a top keeper and has been performing well, but he has struggled to match the form he had a couple of years ago when he was probably the best in the world. That was before he got his injury and something like that will always have an effect.
"I think Rafa will take encouragement from what happened on Saturday and the fact that JT is now also missing. Benitez has to go down there and attack and if they get an early goal it could unsettle Chelsea.
"What's good for Chelsea and Cech is that Liverpool are a different team and don't have the same kind of aerial threat as Bolton. They tend to rely on Fernando Torres to find goalscoring positions and Steven Gerrard to run into the box at the right time to link up play and finish things off.
"What happened on Saturday will actually do Chelsea a favour. They learnt the old lesson that no game is over and never to take the opposition lightly."
