Newcastle have signed Spain Under-21 international Mikel Merino from Borussia Dortmund on a season-long loan.
Midfielder Merino, 21, who made nine appearances for Dortmund last season, becomes Newcastle's fifth new signing since they won promotion back to the Premier League.
"Mikel is a midfielder with talent, an under-21 international for Spain. He's a good size, has quality on the ball and he's very, very focused and professional," Newcastle manager Rafael Benitez told the club's website.
Merino joined Dortmund at the end of the 2015/16 season from hometown club Osasuna, for whom he made more than 60 appearances.
