Great player, but I don't think we should spend on him. And exchanging him for Trez would be a great mistake. I've said it b4 and I'll say it again, letting Trez go would be a great mistake.
Well, since it is likely that Trez will be leaving, we might as well sucker Chelsea into including Lampard into the deal. It will will cut us some money spent on Lampard IMO.
