He was good because x-coach-was-there never makes much sense. So what if he played attacking football? Some other players failed to deliver despite offensive tactics. Lamela did great in Rome and it's wrong to say he's a one season wonder. In his first season he did decent but don't forget it was his first year there and he needed time to settle, not to mention that he was a little kid. After a while he started shining and his price was pretty fair considering his output at that age. What he did at that age was not possible for majority of other players who came to Italy. It was an obvious talent. It has nothing to do with Zeman. He did what he was asked to: had a great pace, was amazing dribbler, was cutting in and most importantly -- was effective at that. When he gets the ball in the midfield he goes forward and gets past 3-4 players, crosses or goes for a goal and scores. It's him who does that. It was not Zemen who used teleport skills to blink him in front of the goal with his superior brain activities.
Fred said why he failed as well. He is not the first, nor last, player who 'failed' in EPL. That still doesn't erase his talent and ability to be great. Actually, it's a fantastic opportunity for clubs to take the gamble and sign him for much less money. And hell, the boy is well worth that gamble. He'd rape in Italy without a doubt and any club will be lucky to have him. He can easily fit in Spain, Germany and Italy. I hope it will be us who will see that and try to sign him (eventhough it's hard to believe we'll even bid).
