Newcastle have signed former Liverpool and Sunderland defender Javier Manquillo from Atletico Madrid for an undisclosed fee.
Manquillo, 23, has put pen to paper on a three-year contract and is the Magpies' fourth summer signing.
"I'm very happy to be here," Manquillo told the club's official website. "From the first moment that Rafa Benitez called me I just knew that I had to come here, to such a big club."
