I have been doing some digging on this and I think my initial thought process was flawed. Isco is obviously a classy operator as he has played at Real but is he as big a name as say VDV as was questioned earlier in the thread?
VDV was a superstar of Ajex and Hamburg, went to Real, had a comparable record to Isco and was also a massive player for Holland.
I would say you are looking at two players in the same ball park in terms of stature.
Isco should have the world knocking down the door for him and it seems he hasn't, so the options look to be Malaga and Us, I think whats making people believe this won't happen is purely because he plays for Real, but its not like we are trying to get Ronaldo, Bale or Modric, this guy is second tier. Real want him gone and the only thing I think that would stop it is footballer ego, that and changing Malaga where it is home for London and the unknown.
