We have Macherano, Pique, Bartra, Busi/Song can play as a CB also, so I don't understand your indignation.
Think first, then speak.
I think his indignation comes from four things:
1. Tito refuses to use Bartra or any other youth product (reasons don't matter, they might be ready or might not be), so he doesn't count.
2. Busi should not be playing CB, he should be where he is the best pivot in the world. Period. He's out.
3. Song is not ready to be a CB yet. While I'm starting to come around on his raw physical potential and his knack for making great tackles, he's not there yet. He's out.
4. So now you have Pique and Mascherano (Puyol we know is an injury risk, and even if he wasn't he can't be expected to play as often as he used to). Two quality CBs, with a conditional third... for a team that is fighting to be the best in the world. That's where the indignation is coming from. It's coming from being able to recognize a potential problem and refusing to address it.
