Considering that Barcelona hasn't promoted a defender to be an active rotational player since Puyol, 21 year old Montoya is still very much a kid - defenders don't break into a starting XI at a massive club like Barcelona
Too many people are myopic in their outlook on player development and think it's commonplace to see sub 21 year olds break into a big club...This isn't a video game, just looks like it...Far different for a young attacking player to slot into this squad than it is for a defender, night & day
Montoya is a terrific prospect who should be the next starting RB for La Furia Roja and heir to Dani's starting position...but seeing that the kid was only promoted a few months ago, I'm sure it'll take some patience to see him develop into a formidable defender/attacker for Barcelona - but the signs are promising that he will not disappoint
