The world has seen whole seasons worth of sneak previews of whats to come from Aguero. If Udinese think they can charge more than Aguero is worth for Sanchez then no one will end up buying him. Udinese should realise that.
Oh I know it probably won't be official until then but from what I heard Atletico want to wrap the deal up quickly so that they know ahead of starting pre-season if he will be around next year or not.
