Chelsea boss Rafa Benitez has welcomed their quick turnaround for their FA Cup tie with Manchester United.

The Blues lost their opening last-16 Europa League fixture with Steaua Bucharest on Thursday night and Benitez is pleased to have a swift change of focus with a key fixture against fierce rivals.

"It's a positive. It's good and it's a challenge for us," he said. "In terms of the focus of the players, it's good. We have an opportunity very quickly to change things.

"It's a good competition, a very exciting competition and Chelsea, as a club and as a team, have been doing really well. Hopefully we can carry on doing well after this game. That means that we will be through."
