Manchester United have splashed out £60million on Argentina winger Angel Di Maria, the club have confirmed.
The player passed his medical earlier on Tuesday afternoon, ensuring he would become the most expensive player in British football history.
Ed Woodward has been forced to pay over the odds for a man who was expecting to spend much of the season on the Real Madrid bench, having missed out on previous targets earlier in the summer.
Louis van Gaal could follow this deal up with moves for Juventus midfielder Arturo Vidal and Ajax defender Daley Blind.
Di Maria said: "I am absolutely delighted to be joining Manchester United. I have thoroughly enjoyed my time in Spain and there were a lot of clubs interested in me, but United is the only club that I would have left Real Madrid for.
"Louis van Gaal is a fantastic coach with a proven track record of success and I am impressed by the vision and determination everyone has to get this club back to the top - where it belongs. I now just cannot wait to get started."
The 26-year-old, who cost Real around £28million when they signed him from Benfica in 2010, is regarded as one of the best attacking midfielders in the world.
His signing is a statement of intent from new manager Van Gaal too.
"Angel is a world-class midfielder but most importantly he is a team player. There is no doubting his immense natural talent," he said.
"He is a tremendously fast and incisive left-footed player who puts fear into the most accomplished defence. His dribbling skills and his ability to take on and beat opponents are a joy to watch. He is an excellent addition to the team."
