Inter Milan boss Claudio Ranieri hailed Julio Cesar after their 1-0 win at Champions League opponents Lille.

Goalkeeper Julio Cesar also returned from injury and performed a series of crucial saves.

"Julio Cesar had a great match, but all over the field we were more attentive and concentrated than in Catania. This is a big step forward and the reason we kept a clean sheet," enthused Ranieri.
