He should be saying 'I need 5-6 world class players - now'.
The problem Wenger will have now is, he goes to a club and offers to buy Joe Average Bloggs (but better than what hes got)..."sure you can have him, £20 mill and he's yours!"
Arsenal needs players quick and everyone will know it!
Ferguson knew who he wanted, bought them as soon as the season finished and took them away on pre-season - result is a ruthless team who will go all the way along with Citeh and Chelsea (who are now building with youth)
