Newcastle have signed Spain Under-21 midfielder Mikel Merino from Borussia Dortmund on a season-long loan.
Sportsmail understands the deal includes an obligation to buy the 21-year-old next summer.
Merino only joined Dortmund from Osasuna last year but became unsettled after making just eight league appearances and is now excited at the prospect of a new challenge under compatriot Rafa Benitez in the Premier League.
‘It feels good and I'm very happy to be here, to be part of this club,’ he said.
