To be honest I think the expectations are to blame. Its not realistic to expect any player in the world to change country, league, club, environment, culture, food, accommodation etc and then perform from day one. It might happen on rare occasions, but the norm is that it takes a couple of seasons. Of course with experience this introduction period can be shortened, but its unfair to write him off based on his performance so far. I DO AGREE, he has not been great, but not appalling either. Given time he will become a key player. But people struggle to allow time. Thats why people eat at McDonalds!
