Actually you would be doing Asa the favour there, giving clubs a year of him not blaming to forget how insanely awful he become, and actually increase his chances to get clubs after getting the Llorente-Bilbao treatment.
The only punishment we can give him is exposure/playing time. But its a double edged sword, a mutually assured destruction for both of us.
If it will be minus it sounds like only 1m less. We bought for 10m and now loaning out for 3m plus 6 option that becomes obligation after some conditions. It makes sense, no one pays that hefty loan fee without getting the player later.
Unless he flops hard like Zaza in West Ham, 5m for half season loan, thank you come again lol.
