I do think that his arrival is conditioned to Llorente's departure. This thing is not going to be resolved now. It will take time.
The kid's priority is playing time. That's why he's leaving Madrid. Why the hell would he chose to be Llorente's backup instead of Benzema's, in his home country and team???
I'd gladly pay 12M + Llorente to Barca for Sanchez. This would be a very good deal. Also, get Nani on a cheap - like for 6/7M, and Morata in a cheap loan + option to buy and buy back clause for Madrid.
Get that guy Siqueira from Benfica for 9M - he looked good against us.
