I'm unsure about going after Mata. I'm a big fan of his, but do we really need him? Assuming Ibra stays that means Villa will be wide left anyway. Then you add in Pedro and Bojan. Buying a young player like Mata would hinder their progress massively. I don't think it'd be a clever buy. Hopefully Valencia will hold on to him, seems like Silva will go so they should keep Mata and Banega at least.
