USA international Freddy Adu is delighted with the chance to train with Rayo Vallecano.
Adu is tied to Philadelphia Union, but has opened the door to signing for Rayo.
"Rayo has been interested in me for a while, before the Gold Cup," said Adu. "My manager keeps in touch with the club and as the season is over in the U.S., I've come to train.
"I love Spanish football. For now I'm just here to train, but it would be a dream to play in Spain."
