I really like Lucas Neill. I think he's rock hard, and it would be great for us to get a wing-back who can actually defend aswell as attack. Much the same with Leighton Baines - great player with an eye for goal and can actually bring some organisation to our defense.
I think i'd be pleased with Upson on the cheap. £2m or so and it's a good deal. He used to be a good defender when Birmingham were a half-decent side. He was always the best English defender out of the usual suspects. The Terrys, the Ferdinands, the Campbells, the Kings, the Woodgates. He was always marginally out of the pecking order.
However, he's had one or two injuries, and i think he's injured at the moment - returning in January.
We could do worse than Upson, and i really can't see us getting much better.
Neill, Upson and Baines would improve our defense monumentally, even merely to increase numbers. Whether or not we can get them is another matter. If Liverpool want Neill, Neill will go to Liverpool. He wanted to go there in the summer but Blackburn held on to him - and since then, his performances have deteriorated somewhat.
I can imagine there'll be one or two teams in for Baines. I think we'd have to be atleast 5 Premiership places above Wigan for him to sign for us, and like Gejon has said, we can give him the cash to come here.
We could get Upson if we wanted him though, no doubt.
