Quique Sanchez Flores has revealed that he is looking forward to a reunion with Manchester United's David De Gea, having given the goalkeeper his break.

Watford host United in the Premier League on Saturday, seven seasons after Flores promoted De Gea into Atletico Madrid's first team, and his former manager, now in charge at Watford, believes he has matured into the world's best.

De Gea was Atletico's third choice when Flores was appointed manager in October 2009 but he ended the season in the first team and close to making Spain's victorious squad for the 2010 World Cup.

Since then he has proved himself a suitable successor to Edwin van der Sar at United and been the subject of intense interest from Real Madrid, but Flores -- whom the goalkeeper grew so close to he bought him a pocket watch as a present -- believes he should remain in the Premier League, and is convinced that his experience in England has been vital to his development.

"I gave David his debut. He was the third-choice keeper and after one month he was first choice," Flores said. "He was amazing. You just need to focus on the training and watch how he is taking the ball and handling it.

"For me he is probably the best goalkeeper in the world. I got a present after two years when we separated, it was a clock.

"The watch is an antique, golden on a chain. You wear it in your pocket. It is very English. I don't remember but I think there was an inscription. I still have it. I won't wear it, that's too much.

"[But] he has everything, he is more than a goalkeeper. He can control everything, the ball in the air. He is good in the goal and out of the goal. For me he is the top three best goalkeepers in the world.

"It would be perfect for the Premier League for him to stay and perfect for him. He needed to come here to learn.

"I've talked a lot about De Gea but with his confidence it will be very difficult to score past him.

"I have [a special relationship with De Gea]. [And] with [David] Silva and [Sergio] Aguero, I wanted to wait until after the game because I don't like to speak to opponents before the game. I try to respect. I don't like my players to see me having a relationship with other players, hugging them. I will wait in my dressing room, for sure. After the game, of course, I will spend time with him."
