We won't be getting Ronaldinho. IMO its completely ridiculous suggesting that.
£8M for Lahm? What planet are you on? He'd cost around twice that and the rest of Europe would be after him if he became available.
Fernandez isn't even playing regularly for Villarreal.
StevieH is pretty much spot on about who is widely rated as the best (seemingly available-ish) players around the world - except, Luis Suarez? I know he's a second striker at Ajax but is he playing that well? And even if he's scored goals - why would he be mentioned above Huntelaar who will have no doubt scored more than him?
Rafinha may be weak defensively, but if we do go for him - our scouts (although they must have watched Voronin) will have watched him more than you, you and you saying he's "crap".
I seriously wouldn't expect anything major this summer. We'll most likely have to sell to buy and with the players we'd sell (bar Alonso) - we won't get much.
I'd expect a flurry of young players again, a few averages *cough* full backs *cough* and then maybe one 12-18 million pound player if the right player became available and that be it.
