Manchester United have announced that they have reached an agreement to sign Crewe Alexandra midfielder Nick Powell on a four-year deal.

The teenage England Under-18 international, who has been linked with both the Red Devils and Liverpool in recent months, has completed a medical and will officially join the former Premier League champions on July 1.

"It really is a dream come true to be signing for Manchester United," Powell told the club's official website. "I have had a great time at Crewe and I would like to thank them for helping me to develop as a player over the past 13 years.

"I'm excited about continuing my development with Sir Alex and the world-class players in the squad. The thought of making the step up to the Premier League next season is an exciting prospect. I can't wait to get started."

Sir Alex Ferguson added: "We have scouted Nick for months now. He is an exceptional talent and has been schooled well at Crewe.

"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 has one international goal for England to his name.
