As I've said a few times I'd like us to be looking at Dario Osorio. He's available for about £15m this summer and will almost certainly end up in the premier league.
Decent with both feet, plenty of pace (especially over the first 10 yards) decent shot, cross and pass and great technical ability. He's one I could see going to somewhere like Everton (as he's been linked to them recently) having a good 18months and then being back on the market for £50m+. For the sort of fee we'd be looking at it's well worth a gamble. His record in Europe is pretty good so his stats aren't just being padded by playing in Denmark.
