He really rates Samba, he was trying to sign him at Tottenham for ages. To be fair Chelsea were after him too for a while, it's probably not a bad bit of business - yes the wages are high but that's what he'd get anywhere else.
Villa as an attacking option and put Iniesta in the midfield. I mean, Fabregas could've subbed in. The sluggish barca defense was really to blame though, just no energy.
