I respectfully disagree. Of course I'm biased up to a certain degree, but the fact remains he was a superior player at Reading, good for Hoffenheim(before their new coach ruined the team) and has been superb for Swansea. Yes he's having a good run of form, but it's not like this is the first thing he's done in the world of football. He's done great everywhere he's been and is now proving he's ready for the Premier League. How can you say it's temporary?
If we wait to watch him do this over the next few seasons, he'll be at United or Inter and laughing in our faces when we show him interest. The point is to buy players before their price tag goes sky high isn't it? Here is a guy who's 22, has all the signs of a wonderful player and is on fire in the Premiership. What's not to like?
