Any manager who has won both the European Cup with a club and the European Championship with his country when he was a player shouldn't need to remind his team of how great he was. In Ronald's case it is just obvious from his relaxed and unassuming manner that he doesn't strut about boasting of past glories, he just gets on with the job, and by all accounts, the players respond to that. I bet he loves having two full backs who can attack in his side though!
