Real Madrid president Florentino Perez has insisted there's no movement on David De Gea's potential move to the Bernabeu.
De Gea, who is entering the final year of his contract at Old Trafford, has been heavily linked with a summer move to Real.
But the Spanish goalkeeper returned to Carrington for the start of pre-season training last week with the two club so far failing to agree on a fee.
Speculation that De Gea is set to move increased over the weekend when Iker Casillas confirmed he had agreed a deal with Porto.
However, the Spanish international was included in the United squad that departed for their pre-season tour of the United States yesterday.
Victor Valdes' agent, meanwhile, has ruled out a switch to Turkish side Atalyaspor due to the player's wish to remain at United.
The Turkish media reported comments by Atalyaspor president Gultekin Gencer in which he claimed that Valdes was keen to move to his club this summer.
Valdes recovered from a serious knee injury to make two Premier League appearances last season as he remained behind David de Gea in the Old Trafford pecking order.
"Some people from Turkey called me to negotiate Victor's signing," Valdes' agent Gines Carvajal said to Spanish newspaper AS. "But I've never spoken to the president of that Turkish club.
"Hence, I'm not going to discuss the comments he made regarding Victor. I don't know him.
"We have no intention of speaking to them again because the player does not want to go to Antalyaspor."
