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."
Meanwhile, Newcastle striker Daryl Murphy has joined Sky Bet Championship side Nottingham Forest for an undisclosed fee.
The Republic of Ireland international, who joined Newcastle from Ipswich last August, has signed a three-year deal at the City Ground.
Murphy scored six goals in 18 appearances as the Magpies secured promotion back to the Premier League at the first attempt last season.
But the 34-year-old was deemed surplus to requirements by Newcastle boss Rafa Benitez, opting to join Forest who were in need of a striker following the departure of Britt Assombalonga to Middlesbrough.
A statement on Newcastle's official website read: "Everyone at Newcastle United would like to wish Daryl well for the future."
