Well I think he made a mistake. Even Ronaldo wasn't playing well for Brazil but the coach gave him another chance and he scored 2 goals against Japan.
Why didn't Van Basten give Ruud another chance?

BTW, Van Basten was one of the greatest goalscorers in world football and I expect him to know that players (especially goalscorers) sometimes go through bad spells. He went through them himself as a player.
