Rio Ferdinand admits this week is huge for Manchester United.

Tonight they face Champions League opponents Otelul Galati in Romania before Sunday's derby with Manchester City.

"If you come out of this week with two wins, you have had a fantastic week and the confidence goes sky high," Ferdinand told manutd.com. "But it can go the other way. That is what you are up against. That is what the demands of this club are. If you can't deal with those demands, the manager won't have you here for long. We have a massive week but one we are relishing."
