Tbh, the only real thing I'm mad about is the extremely low transfer fee. It's become pretty clear to me that for us, as he does not properly fit our system and is not good enough to change it just to suit him, he isn't worth as much as the money we could be getting. Selling him actually makes a lot of sense for us, even if it won't seem so when he'll start to tear shit up next season at BVB.
But 20-25 million for a 24 year old Capocannoniere is incredibly cheap, no matter how you look at it.
