I think Puyol and Pique have to start at CB. Play what players are available in their best positions. I know this will leave RB somewhat weak, but Cacares is not exactly a poor player.
Hopefully Etoo wakes up from his recent malaise also. He was awful against Mallorca, and completely anonymous V Osasuna (though he was probably told not to try fopr any 50/50s just in case).
Nerves are building.
Is there any news on Iniesta and Henry? If both do not play, we all may as well forget about a Barca win.
