Otamendi has his style of playing which is being aggressive while defending and tackling and that's what i like in defenders, rather than always depending on right decision, position.
That's how big defenders play, they are never afraid to risk and that character is vital when you want to build a team that is capable of winning CL, that's called individuality ;)
I don't see that much individuality in stones, neither did in Mangala or Nastasic or Savic or in Lescott. That's what kompany has got and that's why sometimes he was used to make stupid mistakes but in most cases that was why city was winning titles during Mancini period, when in most cases team had to defend 1-0 for 25-30 minutes.
He is the best in tackling, look at his highlights, he is always between making stupid mistake or making a highlight of the match and in most cases, in 95% he is making highlights.
I remember maybe Suarez episode where his tackle was not successful but it was successful against Bale, Marcelo and big number of players.
When you look at Barcelona squad you don't see just good players who know how to play properly, they are individuals, characters and in our team otamendi is one of them who has got that.
PS I think this forum is full of trolls maybe, otherwise it's illogical how can someone question otamendi's qualities, we are lucky to have him. Even yesterday, i didn't count how many head battles he won yesterday, yes that foul wasn't good, but 5 or 6 times he won header it saved us from goal maybe.
