Manchester United boss Sir Alex Ferguson has sealed his first deal of the 2012 summer transfer window by signing highly-rated Crewe midfielder Nick Powell for a fee of £4million. Powell has played over 55 times for the league two side and has caught Fergie's eye after impressing this season with 15 goals in 44 appearances in all competitions. Powell will link up at Old Trafford once the league two play-offs are over. England Under-18 International was only celebrating his 18th birthday two months ago and is clearly a signing for the future, though the transfer fee reflects how highly thought of the youngster is. Fergie has parted with £4million for the midfielder hoping he can be a long-term replacement for the likes of Paul Scholes and Ryan Giggs. The Red Devils have received some criticism recently after the departure of promising youth players with Ritchie De Laet, Matt James, Paul Pogba and Ravel Morrison all exiting Old Trafford. The club will hope that Powell can make an impact quickly in the reserves and become a part of the new youth team that the club are building, with players such as Michael and Will Keane, Ezekiel Fryers and Adnan Januzaj. Ferguson has also been linked with several players such as Dortmund midfielder Shinji Kagawa and Ghanian midfielder Kwadwo Asamoah.
