He was ABSOLUTE finesse. He was very intelligent. He was a bit lazy. He didn't had great stamina and he WON, even if not being stellar, he also always looked like a great lad.
Yet the biggest problem with Berba, it's not Berba, it's what came after him and in part because of him, without being his fault.
Sir Alex played his cards wrongly with Tevez and Carlos it's far from an angel so he played his cards too.
Yet for Fergie to not get that after Cris left, to keep that perfect tandem of Rooney and Carlos for the ages, was silly.
Destroying that tandem, that even made Rooney questioning the path of the club, was the seed that in many ways ended in current United.
It was inevitable to loose Cris, but it was quite easy to keep Wayne and Carlos happy and even add Berba to the mix, he could even convert Berba in some sort of lazy Romario box player and provide him constanctly with the two skill pitbulls, with their natural understanding.
To make things worse, Tevez ended being the catalyst for City to become a real threat.
United kept winning, Berba did his job, later came other great players...but that grinta mixed with talent, big personalities and thelepatic understanding for any ocassion was pretty much broken when Cris and Carlos went and it was never regained.
Shyte happens, everyone had their guilty part in why it didn't worked, but it was quite a turning point in my view. And Berba was in the very middle of it with his price tag and as a wrong signal to a player of the calibre and difficult personality of Carlitos.
