David De Gea admits failed Real Madrid move was 'tough'

Manchester United goalkeeper David De Gea said his failed transfer to Real Madrid was a difficult experience, but it helped him mature.

The shot stopper's proposed move fell through after paperwork wasn't completed in time, and he's since signed a four-year deal with the Old Trafford outfit.

The 24-year-old is currently on international duty with Spain and is expected to start against Luxembourg in Friday's Euro 2016 qualifier.

"I am a guy who likes to put the bad things and difficult times behind me," De Gea told reporters. "I had a lot of tough times and I know what it is. We must move forward, working equally and always strong.

"It's a learning process that gives football hard moments but that make you mature and grow. These are things that you learn in the world of football. You have to keep working and try to improve in every training session.

"Everyone who works for Manchester respected me, I tried to help and I am very grateful to them."

When De Gea returns from international duty, he'll line up in United's trip to Everton on Oct. 17. The Red Devils' will look to make amends for a 3-0 reverse at Arsenal last time out.
