Prepare to be shocked then because there is a loan fee, Barca paying his wages and by all accounts, a mandatory purchase option if he plays in 70% of the games and Barca qualify for last 16 in CL.
I would indeed be shocked.
I'm willing to bet you there is no loan fee.
Also happy to bet Barcelona will not be paying his wages, not in full at least.
Btw, the only senior players we loaned whose wages we didn't pay, were Dzeko and Angelino. Mangala, Adebayor, Bony, Nasri, Negredo, Jovetic, Balotelli, RCS etc, were all reported to have us paying either all or most of their wages.
