In the last minute of deadline day the transfer for Luuk de Jong from Sevilla to FC Barcelona was official. But it wasn’t easy as everything was depending on Chelsea buying Sàul from Atletico Madrid and Atletico Madrid replacing him with no other than Antoine Griezmann on loan. Griezmann left Atletico for Barcelona in the summer of 2019 for 120 MEUR and can opt in to buy him back after the loan period wends in 2022 for 40MEUR.
