atm that's logical ut it's the same story as with montoya or sergi.I'd put masche as my CB over Bartra 10 times out of 10,no joke
if he only is allowed to play as a last resort against mandzukic then he has a problem and won't getting better.
La Masia is useless if your head coach is scared to use the kids. at some point you need to throw them in and give them some games (even with mistakes)
Since Pique's injury you just see Bartra getting better, gain confidence, ... of course he is still worse as warrior Masche.
I still think Bartra, Pique, Masch, Laporte should be a solid defense for the next 2-3 Years if u reorganize the midfield and tactical structure of the team
