Mikel Merino has completed a permanent move to Newcastle United from Borussia Dortmund after an impressive start to his career in England, the Magpies have announced.
The 21-year-old midfielder arrived at St James' Park on loan in July with the possibility of a full transfer included in the deal, and has done so well on Tyneside that the club has handed him a five-year contract.
Manager Rafael Benitez told NUFC TV: "I'm really pleased we have been able to bring Mikel to the club permanently. He has played very well since he joined us.
