David de Gea thanks Manchester United fans for 'unbelievable support' as Real Madrid speculation grows

Manchester United goalkeeper David de Gea has thanked fans for their "unbelievable" support amid mounting speculation suggesting he is poised to sign for Real Madrid.

De Gea, 24, was forced off with an injury in Sunday's 1-1 draw with Arsenal at Old Trafford in what may have been his final appearance in front of the club's home support.

Widespread reports in the build-up to the 17 May game had suggested Real Madrid had agreed terms with the Spain international, while manager Louis van Gaal admitted post-match his goalkeeper has been tempted to return to his homeland.

De Gea himself did not comment on the growing speculation, but tweeted to his 4.58m followers: "Thank you very much indeed for your support. You're unbelievable. I hope the injury is not too serious."

De Gea went straight down the tunnel to receive treatment for his hamstring injury after being replaced by Victor Valdes after 74 minutes. The Spaniard returned from the dressing room after the match to join his teammates in a lap of honour, thanking the home fans in attendance who sang "David de Gea, we want you stay" throughout.

Van Gaal was grilled on the future of his goalkeeper post-match, and while he said the club will fight tooth and nail to retain the player, the Dutchman admitted the chance of him returning to Madrid is a real possibility.

Speaking to Sky Sports after the match, van Gaal said: "With every transfer it is also a process. It is also a process with David de Gea, but he shall not leave us so easily because we are a great club and he wants to participate. But of course he is Spanish and his girlfriend is Spanish. But he shall not leave easily."
