West Brom have completed the signing of Luton defender Leon Barnett for an initial fee of £2.5m.
Barnett made 43 appearances for Luton last season
The 21-year-old, who was Luton's player of the year last season, follows in the footsteps of Curtis Davies who joined West Brom from Luton two years ago.
"We've brought in potential. There are parts of his game he needs to develop," said Albion boss Tony Mowbray.
"We're looking forward to helping him improve and hopefully seeing him play his part in the club's future success."
Barnett made 78 appearances and scored three goals in five years for his home-town club having made his senior debut in October 2002.
His transfer fee could rise by a further £250,000 depending on appearances, plus another £250,000 should he help the Baggies return to the Premiership.
