There aren't many players like Abidal out there, he's a unique player, a kind of Thuram of the left side. It actually happened that we have 2 attacking minded fullbacks and it's Alba that has performed better in this way (attacking), i already know he's not that good defensively but neither Alves is. As i said they are both attacking minded so we should firstly judge them in that way. And because Alves has been inferior he needs to be off the line up. Not to mention that he lost much of his speed. We need to have one defensive minded RB and Montoya should be the one, he just needs to be trusted in order to be improved. Playing like some games without a true stable place could be a result of not so good performances but he was good last season whenever he played. We should judge him when he gets a full season as a starter.Wouldn't it be great if we had tall, strong left back that's better than alba defensively anyway and can play at CB very well? Hmm ...
