I didn't even refute your point, just the line of defense used in last few days is pathetic and using that you can't have any meaningful conversation with anyone.
I don't think anyone is blind to not see Blind is not a CB. People saying we are fine with CBs are basing their opinion on playing Smalling with Jones or Rojo and supported by midfielders like Schweinsteiger and Schneiderlin.
Even if we sign right footed CB, Van Gaal would have played him with Blind as Rojo missed preseason. Problem is not with squad, it's with manager and his clueless experiments.
The issue is that Rojo missed pre season. And as sunil points out, unless this defender is two footed (Hummels), he is playing on the right.
