Didier Drogba says Chelsea could have scored more than the four goals they did get in last night's victory at Rosenborg.

"We can always improve, and I think we could have scored more goals, but we are happy with our performance," he said.

"We're a team of big players and we had a bad run of games, but we've shown now that we are able to bounce back.

"We blocked them out of the game and prevented them from playing their game.

"We have to keep winning and grab points."
