It is somewhat shocking that despite 'being' with West Brom for three seasons, nobody really associates Borja Valero with the Baggies. One of the reasons behind this might be the fact that he played only one of these three seasons at The Hawthorns, trying in vain to save the club from relegation. A talented midfielder like Valero, who was developed at the Castilla, could not accept playing in the second division, and forced a loan move to Mallorca in 2009-10.

It was a wondrous season both for the player and the club, as Mallorca somehow managed a fifth place finish. A permanent transfer was on the cards, but Mallorca apparently could not afford a paltry £2.5 million. The next season, he was loaned out to Villarreal, with whom he signed a permanent contract after his contract with West Brom ran out at the end of the season.

He appeared 31 times in the league for the West Midlanders, failing to score a single goal.
