He usually played out wide left but had a tendency to drift inside and wind up receiving the ball with his back to goal, taking up the traditional number 10 position - hence his knack for scoring goals. He won't really beat a man for pace, he won't take a full-back on and run past him. He's more tricky and technical... He can also strike a dead ball well.
The big problem I had with him was a lack of desire. I know it's a 'perception' thing but I just felt like he didn't put in the extra effort. He was knocked off the ball very easily at times and didn't try and redeem turnover situations that he caused. I don't think you can get away with that kind of mentality in the EPL. For example in the final of the Asian Cup, playing against a very physical Australian side, he was the definition of a shrinking violet and I believe his attitude/mentality has been questioned at times by the Leverkusen faithful - mind you that is second hand information from very biased Australian commentators, so make of it what you will.
There's a chance Poch could be able to reform or reinvigorate his attitude as he's young and very capable - he looks very fit. I think he could turn out to be a good player for us, but I also think there's a chance he won't make the grade in the Premier League. One firm challenge, one lack of effort on his part and he could wilt under the pressure from our fans.. Like most things it depends how quickly he can adapt to the intense physical pressure of the EPL.
