WTF? People are questioning Sergio's quality?
I tell you now the only reason this is in question is because a LOT of people hate him and cannot stand the sight of him.
I, like most, dislike Real Madrid as a club however I have always admired Ramos. He is a complete leader, a HUGE influence on his team mates, a winner, a player that embodies more than his single position on the pitch.
The simple thing to ask yourself is, how on earth would he have won that many trophies and more importantly how would Real Madrid have won so many trophies and put up with him if he were even remotely a substandard centre back? It's an unforgiving position and one that no club allows passengers in, least of all Madrid.
