The Spanish shot-stopper has been in fine form for Louis Van Gaal’s side this season, continuing his development into one of the world’s best goalkeepers.
That has led to persistent rumours about interest from Champions League holders Real Madrid (per the Telegraph), who will at some point have to replace long-serving stalwart Iker Casillas, and Owen says a move may interest the Spaniard, while admitting that United must do all they can to retain his services.
“Now you’ve got him, then try to keep hold of him,” he said.
“That will be hard, like most Spanish players they come and have a sample of the Premier League but really, Real Madrid and Barcelona is where they want to be.”
Former Liverpool and United forward Owen also believes that the youngster is in the top three goalkeepers in the world already, having proven himself in the Premier League.
He had initially struggled under former manager Sir Alex Ferguson following his move from Atletico Madrid, with many labelling him a flop, although he has since established himself as the undisputed number one at Old Trafford – with the arrival of compatriot Victor Valdes doing little to affect his standing.
Owen believes it would now take serious money if the club were to sell De Gea.
“I think he’s developing into one of the best in the world,” he added.
“He’s probably in the top three already, he’s very young and proven in the Premier League. If you go and try to replace him you’re going to have to spend 30/40/50 mil, plus wages.”
