Sir Alex Ferguson is adamant that forward Wayne Rooney will still be at Manchester United next season.Former United assistant manager Steve McClaren told Sky Sports News on Thursday that he expected Rooney to stay at Old Trafford. McClaren said: "Sir Alex always says there is only one way to go after Manchester United, and that's down. He's right, that's proved. "There are only four or five clubs that you could say to leave Manchester United to go there and it could be seen as progression. "I know Wayne Rooney and all he wants to do is play football and win, all he wants to do is win trophies. He is a winner and there is no better club to be at than Manchester United if you are a winner. He won't want to leave unless told he can leave. "Going abroad? There are other big clubs. For the moment, I can't see his future beyond Manchester United." Manchester City manager Roberto Mancini also does not think Rooney will leave United in the summer. "I think that Rooney is one of the best strikers in Europe but I think it is difficult he can leave Man United - I don't think [so]," said the Italian.
