I think you can only be world class if you have proved yourself in deifferent leagues and internationally.
Using that logic questionmarks would be placed over proper world class players like Ronaldo and Messi - neither of whom have reproduced their club form for their country
And Messi has only played in the spanish league
Rooney has on the whole been massively disappointing for England but it's worth remembering that arguably his finest hour was in an England shirt in Euro 2004
Emp has it right on this one - an on-form Rooney is a world class player.
We might not like it (personally I think he's probably the most repugnant individual to have ever worn a football shirt and i wish him nothing but ill will) but I don't think we can really question his quality
Fernando Torres was certainly world class during his first two seasons at Liverpool - we might hate him now but surely noone would argue against that
He looks anything but at the moment - and long may it continue
