David de Gea has once again been linked with a move to Real Madrid

David de Gea says he is happy at Manchester United and would not talk about a potential move to Real Madrid in the summer.

The end of FIFA's imposed transfer ban on Real has sparked fresh rumours that the Champions League holders will once again attempt to sign the Spain international goalkeeper.

Madrid failed to sign De Gea after an administrative error in the final moments of the summer transfer window of 2015 saw the deal fall through.

Speculation regarding De Gea's future has failed to go away since and from July 1, Madrid can once again purchase players.

However, the former Atletico Madrid keeper would not be drawn into talking about his long-term future.

"The future nobody knows," De Gea told AS. "The future is the future. I'm very happy here, it's a great club. In England, football is enjoyed a lot."

When pressed about a move to Real Madrid in the summer, he said: "I'm not going to talk about that.

"I will not talk about that subject any more. I just have to keep focused on my club."

Manchester United take on Watford at Old Trafford on Saturday

De Gea and Manchester United take on Watford on Saturday at Old Trafford and have the chance to displace Liverpool in fourth place before their evening match with Tottenham.

United lost the reverse fixture 3-1 in September but are currently on a 15-game unbeaten run in the league.

It is currently the longest undefeated streak throughout all of Europe's top five leagues, one ahead of Barcelona.
