Sup, just a unbiased comment from a Swede, Rasmus Elm sure is a good player no doubt but he wont have much to do in EPL. We aint talking about a starting man, or even one for the bench. Since the pace in Allsvenskan is pretty slow he gets alot of time, and can easily defend himself and the ball. When he met one experienced midfielder he got eradicated from the field, he just doesnt have the skill atm to play in EPL in one of the best teams..
If you sign him for the youth team and for him to learn for a couple of years, then you made a great buy as his value will rocket up. But at this very moment the move from Allsvenskan to EPL is far to great, he will get screened away and most likley drop alot of balls due to hard pressure.
