I hope we get a lot more than £20 mil for Dzeko if he does go to Bayern. He has one of the best goals/minute ratios in the Prem, and he's scored a lot considering the team isn't set up in a way he'd really shine. Yes, there have been some shocking bad games from him, but when he's on fire he is unplayable. Why should we lose money, and quite a lot of money, for him?
For what it's worth, I think Javi Martinez will be lured to Barca, and we'll have to bust a gut to get Bale, though it wouldn't be impossible. Funnily enough, I think the RVP transfer is the one most likely to happen, as long as we can convince his missus.
