The Italian refused to be drawn on speculation about Drogba's Stamford Bridge future and once again backed the misfiring Torres to come good.
"Obviously, for a striker it's important to score," he said of the latter, who once again failed to find the net in Copenhagen.

"He had four opportunities to score and was denied by the goalkeeper and he moved very well for the team.
"He'd have preferred to score, but he will."
