That's not completely true. He's not that outstanding as in Lille, but he has had a lot of very good games for Belgium. Problem is that a national team is always more difficult for the big stars, when also other players can decide games (look at Van Persie, Messi, Ribery,...). It's a little bit searching the right way to play together without a lot of training. In Belgium, people expect him to lead the team, create openings, dribble 3 players, give the assist and score the goal. Three times per match. Well, that's not realistic. He has not had a lot of exceptional games (some, but not a lot), but also never a really bad game. He didn't play a lot with the previous coach (only 2 or 3 matches in the starting 11), but he still was decisive in a lot of matches.
