The 22-year-old is joining the Black Cats on a loan deal, but in case he makes more than 25 appearances this season, the English club will have to pay Atletico €16m for a permanent transfer.
This is Manquillo’s third straight loan, since he spent the 2014/15 season at Liverpool and the 2015/16 at Olympique Marseille. His year in France was reasonable, but Marseille didn’t buy him because the €25m clause was considered to be unaffordable for the club.
Mundo Deportivo says the Atletico fans are surprised he can’t get any chances at the club. Manquillo has a contract at the Vicente Calderón until 2018, and will be returning to the club in case his season at Sunderland doesn’t reach the number of games set in the contract.
