De Gea has been consistently linked with a move to Real Madrid all year long but with the pre-season tour less than three weeks away, the Spaniard is still a Manchester United player.
Since his arrival at the club, Mata and De Gea have been extremely close friends because not only were they compatriors, they were neighbours too.
Everybody wants to know what is going on with De Gea but when asked by Ruud Gullit in an interview with BeIN about whether he was joining Madrid, Mata declared he still didn’t know what was going on with his potential move to Spain.
“I don’t know, I don’t know,” he said.
“You want me to tell you? I don’t know. I wish the best for him but as a team-mate, I would like to have him but I don’t know.”
Given that De Gea and Mata have been such close friends for years, it would be somewhat surprising if Mata genuinely had no idea about whether he is leaving this summer.
That being said, even if he did know, the last thing he would do is go and talk to the press about it with De Gea staying so quiet with regards to his future.
With his current contract expiring next year, De Gea could leave on a free transfer if he is kept by Man United this summer but the club are in no rush to sell him.
Fans have already somewhat conceded to the fact De Gea is leaving this summer but up until the point he is holding a Real Madrid shirt, there is still the possibility he will stay beyond this current transfer window.
