Put Messi in the Manchester United side and he wouldn't be as good as he is now.
Put Rooney in the Barca side and he wouldn't be as good as he is now.
They are both great player, but both great in different ways.
Messi is the present king because Barca triumphed in the CL last season, but that could change this year.
If Ferguson had gone up against Barca in the same way we did we might not have to suffer half of Britain tossing themselves off to Messi right now. But Fergie got big-headed, had a lesson and we now have to put up with the worship.
For all the histrionics over Barca, they aren't even leading the Spanish league. When they win the league and CL for the second time in a row then they can start worshipping Messi, but they could end up looking foolish if Barca win nowt.
