Chelsea boss Carlo Ancelotti insists they can be patient tomorrow night in their Champions League return-leg clash with Inter Milan.

The Blues need to score and to win to overcome the 2-1 deficit from the first leg but with a single strike enough to go through to the quarter-finals, it is just as important to keep the Serie A side away from our goal over the 90 minutes.

"I don't think we have to score early," Ancelotti told chelseafc.com. "We need to play well, in a game with balance, because then we can still score in the last minute of the game.

"We want to start the game well and play well but we don't need a goal straight away.

"The Champions League takes out a lot of energy," he continues, "not only physically but mentally and it is not easy. But we have to do a very good job to maintain concentration in every game."
