West Brom have completed the signing of Borja Valero from Real Mallorca for a club record £4.7million. The 23-year-old midfielder has signed a four-year contract after passing a medical. Spaniard Valero is the Baggies' ninth signing of the summer, taking their close-season spending past £20million. Manager Tony Mowbray said: 'I'm delighted to welcome Borja to the club. 'From a footballing point of view he possesses many of the attributes I like in a player.' Mowbray said he believed Borja may need a little time to adjust to the Premier League, and that despite a record fee was not guaranteed a place in the team. But he added: 'Borja can link up the play from back to front and he will enhance the excellent midfield options we already possess.'
