Lucas Neill. Seriously, he's a quality player with a never-say-die attitude, he's a battler. He's a right-sided CB (I'm saying we should get in Lescott for the left sided CB, this is in addition to him, not instead of) who is versatile in that he is also fully capable of being competition for Zab and Micah at RB too. He can cover left-back too if ever needed to do so. He has premiership experience. He is 31 and so offers quality now but will be moving aside in time for Micah and Ned to become complete players. Seriously, what's the catch?
I feel that although the Terry saga will run close, he probably won't come (not being negative just my opinion) so Lescott and Neill would be quality additions.
