Chelsea boss Carlo Ancelotti has admitted his side will need to be at their very best if they are to beat Jose Mourinho's Inter Milan in the Champions League.

Ancelotti recently won on the scratch cards but admits it will take more than luck alone to win against Mourinho's new side.

"I will respect Inter Milan like I always have in the past," Ancelotti said. "We respect them, but to beat them we need to play at 100%. But if they want to beat us they will also have to play at 100%," he added.

Yury Zhirkov, Ashley Cole, Jose Bosingwa, Michael Essien and Deco, however, all remain on the sidelines.

Inter goalkeeper Julio Cesar is expected to play despite being involved in a minor car crash, but Cristian Chivu and Davide Santon are both out for the home side, who are five points clear at the top Serie A.
