Derby County have pulled off a coup by signing midfielder Omar Mascarell on a season-long loan from Spanish giants Real Madrid.

The 21-year-old made his La Liga debut when coming on to replace Mesut Ozil in a 4-2 win over Osasuna on the final day of the 2012/13 campaign and has been a regular starter with the club's B and C teams.

Mascarell, who travelled with Real for the International Champions Cup in America and featured against Roma and Inter Milan, has represented Spain at youth level, as well as being called up by Equatorial Guinea for two World Cup qualifiers before declining to play.

Rams boss Steve McClaren said: "We're delighted that we have been able to bring Omar Mascarell to Derby County on a season-long loan deal. He is a talented young player and I have monitored his progress for a number of years after first coming to my attention whilst in Holland at Twente.

"Our head of football operations Chris Evans has worked tirelessly to get this deal over the line and spent a few days in Spain thrashing out a deal with Real Madrid. We would like to thank Real Madrid for allowing Omar to spend the season with us and are looking forward to working with him."

Chief executive Sam Rush said: "I am delighted with our relationships with some of the top clubs in world football and we have established a good working relationship with Real Madrid. We look forward to that continuing long into the future."

Described as a 'thinker' with a good football brain, Mascarell joins fellow Spain youth international Ivan Calero at Derby.
