Putting wages to one side (not possible in reality, I accept), Remy and Maloney are probably the only two who really stand out for me.
I wouldn't say no to McManaman, but he needs to do a lot more yet before I start jumping up and down, eager for us to sign him. And whilst I rate Kone, and wouldn't have any problem with us signing him either, I want us to sign a 20+ goal a season striker who is of top 8 quality - and I don't believe that Kone is one of them. And on that basis, I see no reason to sign him as well, when we already have Rickie and Jay.
McCarthy at Reading is decent, and unlike people with McMananan, I'm not saying that based on this season (or even just this week!). He's impressed me before, included during a loan spell at Leeds if I recall rightly. But do we need him? I'm not sure. I'd need to see him (ideally live) on a regular basis, to really assess his kicking distribution (which is the one area I believe Boruc lacks in).
