25M for Iturbe is definitely overpriced, but he actually has great potential.
Plus we're dealing with Verona, who could accept 4 or 5 installments (Sanchez would require at most 3 installments). Plus his salary will be of around 1.5M net (If Sanchez would get 4.5M net - it's a 6M gross difference per year - lots of money).
So Iturbe is actually much much cheaper than Sanchez, thus attainable. I hope we get him.
