I can (sort of) agree with part of Dazz's argument re: the quality of service...pretty much any striker playing for Man U will score more goals than if they were playing in most other teams (except Forlan

) simply because they create a lot of good chances.
Van Nistelrooy is just a different type of striker to say Henry, Shearer, Owen etc. To be honest he reminds me a fair bit of Ian Wright in the way he seems to be in the right place at the right time.
