hmm I believe United has a 50 % sell on clause, so assuming it’s on the full amount of his next transfer, he’d need to sell for 50m for Betis to just break even.
No these sell on clauses always count on transfer-win so if they sell for 50 million betis gets 37,5 and united 12,5.
Worked the same with nico gonzalez to city for us, for example.
But 25 million for antony is very cheap if if you deduct his high United salary. If there is a la liga with his stats in the second half of last season he would normally leave for around 50
