Criticism is fine as long as it is constructive, and not just generalising by saying this guy is "terrible" or "good". This is a young guy who has lot of potential and remember he scored more than once in Chelsea's net with his previous team. He is dangerous and knows how to find space. But for him to shine, he needs his mates to cope with his speed so they can use the chances he creates for them (thinking for instance about the couple of dangerous passes he made to Torres and Hazard against Cardiff) and reciprocally pass to him when he is moving quickly behind the opponent's lines. He definitely needs to improve his finishing which was obviously poor against Cardiff. Once this finishing issue is fixed (hopefully during pre-season) we will then see one of the most effective players in EPL next season. If he doesn't fix it, then we will most probably see him only on the bench or loaned to another team.
