Sunderland AFC have completed a deal to sign Atletico Madrid full-back Javier Manquillo.

The 22-year-old Spaniard becomes David Moyes’ sixth signing of the summer after joining from the Spanish giants.

Manquillo is no stranger to the Premier League having spent the 2014-15 season on loan with Liverpool.

The right-footed player has represented his country at youth level up to under-21 and has both UEFA Champions League and Europa League experience with Atleti.

He spent last season on loan with French giants Marseille, gaining further European experience.

The agreement is a season-long loan initially, which includes an option for Sunderland to make the move a permanent four-year deal after the completion of the loan.
