Sunderland have confirmed the signing of Atletico Madrid defender Javier Manquillo on a season-long loan.
The Black Cats also have an option to make the move permanent at the completion of the loan. Sunderland and Manquillo have agreed a four-year deal, should a permanent transfer be pushed through.
Manquillo has been recruited by David Moyes as he looks to rebuild his Sunderland side and avoid another battle against relegation.
The 22-year-old has played in the Premier League before - he spent the 2014-15 season on loan with Liverpool, playing 10 games in the top flight.
