Manchester United goalkeeper Victor Valdes is looking forward to another season at Old Trafford, despite fresh doubts over his future at the club.

Valdes, 33, is a notable absence from the 26-man squad that left for a pre-season tour of the United States on Monday 13 July.

His omission prompted speculation he is not part of Louis van Gaal's plans going into the 2015-16 campaign, despite David de Gea's future at the club also being in doubt amid continued links with Real Madrid.

Valdes, along with Rafael da Silva who was also left out of the travelling party, will continue his preparation for the new season at Carrington, but the goalkeeper has shown no signs of discontent, tweeting: "After a hard training session this morning I am working hard for this season. Come on you Reds."

Valdes signed an 18-month contract with the Premier League giants in January with the option to extend that by a year, but has featured just twice for the club, stepping in for the injured De Gea in the club's final two games of last season.

Turkish side Antalyaspor claimed on Friday 10 July they have made an official bid for the ex-Barcelona shot stopper and were hopeful of completing a deal "within a couple of days".

However, Valdes' agent Gines Carvajal quashed such rumours, confirming that while he has been contacted by a number of representatives from Turkish sides, his client has no interest in a move to the newly promoted outfit.

"I've been contacted by a series of individuals from Turkey to negotiate a move for Victor," he told Spanish daily AS. "But I haven't spoken with the president of the Turkish club in question. I don't know him. I have no plans to talk with them again as my player has no interest in a move to Antalyaspor."
