Its not like every player in the EPL can bring a ball down like Ronaldinho. Ive seen far worse control from "EPL Quality" players
also he's only 21 - so his touch should get better the more he plays at a high level.
He doesn't have to be Ronaldinho, but his first touch is bad, and that's been apparent on a fairly regular basis (even against inferior opposition from the Islands). It's something he really ought to have fixed by now and if he hasn't by now - at 21 he's got a little room for improvement, but not a hell of a lot. He won't be a 'young' player much longer.
His best chance of playing in the Premier League is to get promoted up. Even then he'll have to compete against new strikers, as promoted clubs generally try to get forwards with Premiership experience to strengthen when going up. The history of prolific Championship forwards making a successful step-up to the Premier League hasn't been very good in recent years.
Having said all that, good luck to him and hopefully he keeps up this scoring spree he's been on.
