Kochen had, in fact, already reached an agreement to renew his contract with Barcelona on February 2, 2024, but it had not been signed as the club were adamant that Kochen sign it only once he turned 18. The young player turned 18 in March, but has yet to finalize the necessary paperwork. According to Mundo Deportivo, the formal signing of his new contract, which will run until 2028, is expected to be completed shortly.
