Bold 1: He's not, his long shots are horrible. Even so horrible they won't even make the highlights of the match on television.
Bold 2: He's not like this for the Dutch NT, so he can play tikkie-takkie. I only doubt he has the vision for Barcelona. He sometimes starts with something without having any clue what he's doing. He often manages to get himself out of such situation beautifully in the Dutch Eredivisie, but he won't at a higher level.
There is nothing wrong with his longshots. The only thing that he needs to improve is his efficiency.
You are correct that at PSV he keeps the ball longer compared to his playstyle at the Dutch squad. It has to do with the quality of the players around him. Good players offer more options to pass. Thats why Im confident that he will adapt his playstyle to that of Barca. Guardiola will make sure of that. I disagree with the comment on Afellay sometimes not knowing what he is doing. When he keeps the ball with him and starts an action, he either wants to move towards the goal or temporise with the purpose of releaving the team from the pressure of the opponent.
