Really? I haven't paid much attention to Udinese over the years, but according to wiki he scored 21 goals in 112 appearances. Hardly outstanding by any measure.
Probably an unpopular opinion, but there is no way I would pay 27 million for Alexis Sanchez. May be because forwards (as opposed to attacking midfield players) always struggle at Barcelona, but he's looked fairly average to me.
That's what 8 million gets you these days, a slightly above average Premiership player. Yet somehow our lot balk at the idea of ever shelling out such an amount for their top target(s).
