Valero joined the Baggies two years ago from Real Mallorca but struggled to adapt to the Premier League and spent last season back on loan at his former club. The 25-year-old has made it clear he wants to return to Spain on a permanent basis. A West Brom club statement read: "Valero has been given permission to travel to the Spanish club for a medical and to train with them while discussions continue. "He rejoined West Brom for pre-season training last weekend following a season-long loan in La Liga with Real Mallorca. "But after returning to Albion, he has expressed a strong desire to continue his career in Spain for professional and family reasons. "Albion rejected an offer from Sevilla for Valero last month but agreed to meet Villarreal yesterday for talks on a possible deal. This dialogue is ongoing." According to Villarreal, Valero has agreed a five-year deal at El Madrigal. A statement on the Villarreal website read: "Barring a few minor details, Villarreal CF and West Bromwich Albion have come to an agreement for the transfer of footballer Borja Valero, who will belong to the Yellow Submarine club for the next five seasons. "After the signing of the contract and the medical tests, the club will make official the date of the presentation of the footballer." Valero progressed through the ranks at Real Madrid before moving to Mallorca in 2007. The midfielder spent just a season with the islanders before West Brom snapped him up for a club record £4.7million. Valero signed a four-year contract with the option of a further year but was loaned back to Mallorca after just one season at The Hawthorns. The 25-year-old impressed on his return to Spain, winning the prestigious Don Balon award for the best Spanish player.
