As much as I know some people don't like to admit it, Robinho is not in the same league as Messi. Messi is an untouchable player of the kind where if he signed even for the 'mighty' united, it would be world wide news which people would never have thought would happen. He has no requirement to sign for us, as we're not ready for a player of that status yet. Robinho was different, he hated Madrid full stop. The fact it was only Chelsea in for him though tells its own story that he is not a worldstar player like Messi is. If we got Messi it would be headline news of the likes no club has ever been able to make. It would be like Notts COunty knocking on our door and asking for Robinho if you like, because that is what we are in comparison to Barca.
