For the same reason Spurs bought Lennon, Arsenal bought Oxlade-Chamberlain + Walcott and Chelsea bought Moses. He might be very raw but if it is true that Wenger and Sir Alex both want him then it generally means you're looking at a British player with real potential. Ramsey, Powell, Oxlade-Chamberlain, Smalling, Jones - every one of these players looks or looked to have the potential to be a top class player. We tend to do well when we sign British players anyway. Since 2006 we've bought Carrick, Hargreaves, Smalling, Jones and Powell which is pretty good going. It's when we've went for the young foreign players we've screwed up, we've tried to find another raw, talented young winger in Tosic and Obertan and now it's time to go British. When Giggs leaves we'll need another body out wide and Valencia and Young will be 28 by that time so we need another young player to balance it out.
