Spanish media had reported that relations between the two clubs were broken when the player arrived to sign a contract with the Primera Liga side on Saturday, only to fly home the next day after failing to reach an agreement.

"In reaction to reports published recently Valencia continue to maintain good relations with Benfica president Luis Felipe Vieira and the player's representative," Valencia said on their Web site on Monday.

"The club are continuing in their efforts to sign the player."

The 26-year-old winger, who has won 50 caps for Portugal, has been at Benfica since 2001. Before that he had an unsuccessful two-year spell with Barcelona.
