Nope. Abidal, paired with Pique, was a much better defender than Masch. So is Puyol. Any good cb will play better than Masch at the position, for having trained there all their lives, unlike masch, who's been on that spot for only 3 years. Song as cb was a failure, proving your logic of a dm being a good cb for barça mistaken. Masch gets found out for his lack of awareness and positioning. Not just because of the lack of pressing. The lack of pressing just highlights he is not a cb. Against most la liga teams he will do fine, but when facing bayern, rm, chelsea etc, he'll be again a liability. On the friendly against bayern that was already clear again. That experiment has gone for too long now, a club like Barça should have proper defenders.
