Found this article about Marta, sorry it's in Spanish.
The title says "The Importance of Being Marta Tornel".
Basically they say she met Ferru through Javi Piles's wife, she comes from Bonifaio, her parents have an optician's shop where she still works.
She brought a lot of emotional stability to Ferru, who had suffered much from the break-up with his previous girlfriend.
She is beautiful in and out (they say she was ranked 3rd in the hottest WAGs contest - no need to be a professional model - or maybe they mean among the WAGs who were not professional models? not sure)
She's not the usual tennis WAG, and they're not hiding their relationship but still manage to stay away from media hype.
