Mikel Merino joins Newcastle on loan for season from Borussia Dortmund

Newcastle have signed midfielder Mikel Merino from Borussia Dortmund on loan for the season.

Merino, 21, becomes the fifth player to join Newcastle this summer following the arrivals of Christian Atsu, Florian Lejeune, Jacob Murphy and Javier Manquillo.

The Spain under-21 international made nine appearances for Dortmund last season after joining from hometown club Osasuna at the end of the 2015-16 campaign.

"It feels good and I'm very happy to be here, to be part of this club," Merino told Newcastle's official website. "I'm looking forward to touching the ball, meeting my new teammates and starting to play football.

"I know it's a great club and a really nice city. I had different options but I think this is the right place for me to play."

Newcastle manager Rafa Benitez added: "Mikel is a midfielder with talent, an U21 international for Spain. He's a good size, has quality on the ball and he's very, very focused and professional.

"Hopefully he's the kind of player we can improve a lot -- he certainly has the mentality to get better and better.

"He comes from a top side in Dortmund and although he did not play too much last season, he was signed as a young, talented player and to be signed by a club like that shows that he has something good. He has to show what he has, and hopefully he can enjoy playing here for a long time."
