And who in the world can replace Ronaldo, no one.
Only 2 who are close to his level are Ribery and Pato, both who would cost 40-50 million and aren't proven in our league, country or club; that is quite an expensive gamble.
Aguero doesn't play anything like him.
Who knows what Fergie has planned in terms of tactics and formations or even future trasnfers, the fact of the matter is we don't even know how much money he has been given, all we have is newspaper specultation which is rubbish at best.
I'd much prefer to trust Fergie and our coaching staffs opinions rather than someone who would seem to have been happy so long as we spend 30-40+ million.
