Manchester United boss Sir Alex Ferguson says he won't rush Louis Saha's return from injury - despite his performance at Arsenal on Saturday.

Ahead of tonight's clash with Dynamo Kiev, Ferguson said: "We saw on Saturday how Louis can change a game.

"We just have to monitor how he is because we are never going to risk his availability for the rest of the season if we can avoid it.

"If it means starting with him as a substitute, that is what we will do because he is such a different player to any of the rest we have here."
