The Dutch midfielder has labelled his international teammate a game-changer.
Manager Louis van Gaal secured the 21-year-old Holland international last month, with him having enjoyed a stellar season with PSV Eindhoven as they won the Eredivisie title.
He also finished as the league’s top scorer and leaves the club with 43 goals in 106 appearances, and Blind believes he is a game-changer, having worked closely with him while on duty with the Dutch national side.
“He is a player who can change games,” he said.
“He has a great free-kick, a great dribble, a great shot. He’s young, talented and always wants to work hard. He always wants to better himself on the training pitch, that’s how I know him.”
Away from Depay, the midfielder admits he is looking forward to an extended break once the latest round of international fixtures are completed.
It has been a busy campaign for Blind, who was a regular starter in the World Cup before moving to Manchester United, where he has been asked to play in a number of different positions by manager Van Gaal.
His first season in England can be considered a success, though, with his new side returning to the Champions League at the first time of asking, although he does admit it was a long year for him.
“I’m really looking forward to it [the break],” he added.
“It has been a long season after the World Cup. A new environment for me, a new league for me, and the Premier League and me is hard, it’s fast. I’ll like the break now which is coming up.”
