David Winner's take(author of Brilliant Orange) from an article by Ben Lyttleton.
"One of the hallmarks of van Gaal's career is that he is very good at persuading players to adapt to a role they might not have thought of playing," David Winner, author of
Brilliant Orange: The Neurotic Genius of Dutch Football, told SI.com. "He is not quite as rigid with his 4-3-3 as everyone thinks he is. He likes his system, but he knows formations are fluid anyway and what also counts is attitude, energy and state of mind."
Winner interviewed Rooney in 2012 and was struck by the English forward's intelligence. Behind the lurid headlines and salary disputes, he found a thinker about the game, and someone whose appreciation of space and movement came from studying former Ajax (and Liverpool) forward Jari Litmanen. Rooney described himself as like a snooker player always thinking three or four shot (or passes) in advance. This will strike a chord with his new coach.
"What van Gaal likes best about players is their intelligence: Rooney and van Gaal are both highly intelligent, and so I don't think it will be too much of a problem," Winner said. "His teams are all about movement and space, and though they are very precise, at the same time there is an unpredictability and energy to it which tends to win matches."
