Powell last season scored 16 goals in 45 matches to attract Premier League interest and has, to the obvious pleasure of manager Sir Alex Ferguson, signed a four-year contract with United, though he will not return to Crewe on loan.
“He is an exceptional talent and has been schooled well at Crewe,” said Ferguson. “I’m delighted he has chosen to come to United. He has a lot to offer and we are all looking forward to working with him.”
Powell, whose transfer fee could rise to £6m depending upon his success and the number of appearances he makes, shared Ferguson’s excitement. He said: “It really is a dream come true to be signing for Manchester United. The thought of making the step up to the Premier League next year is an exciting prospect. I can’t wait.”
Powell’s arrival follows that of £12m Japan international midfielder Shinji Kagawa, who signed from Borussia Dortmund.
