Van Nistelrooy really was brilliant. Not quite in the same class as the best strikers around at that time - they were monsters, unlike these days - but he was a supreme goal scorer and really intelligent in every single thing he did on a football pitch.
I remember he did his cruciate just before he was due to sign for United and ended up spending another year at PSV. They said at the time that he lost just a touch of speed and mobility off the back of it, God knows how many more goals he might have scored had the injury not happened!
Would be easily the best Number 9 in the world if he were playing today, in my opinion. By a mile.
