The Spaniard was on the verge of joining Los Blancos on deadline day last year, when a reported technical glitch caused the love to break down. The 25-year-old remained in Manchester, helping his side to FA Cup glory after signing a four-year extension on his deal.
Yet it seems the Galacticos are set to make a move once more for the talented gloveman, who says he’s unaware of any interest and maintains that he’s happy in England.
"I know nothing about Madrid wanting to sign me. I'm calm. I have three more years in Manchester," De Gea told Cadena Ser.
"United have given me everything. Now I'm just concentrating on the Euros and to be with the national team.
"I'm at a big club, which gives me love every day.
"I'm very grateful for Manchester United and I'm very happy there."
De Gea, who has won United's Player of the Year award for three consecutive seasons, is part of Spain’s Euro 2016 squad who are looking to defend their continental title at this year’s championships in France.
