West Brom have released Slovenia international Robert Koren after opting against taking up the further year's option on his contract.
The 29-year-old was signed on a Bosman from Norwegian side Lillestrom in January 2007 by then-boss Tony Mowbray. He helped the Baggies reach the Championship play-off final in his first season, losing 1-0 to Derby, before winning the title the following year.
Koren started all-but four games as Albion suffered relegation from the Barclays Premier League at the first attempt and has since slipped down the pecking order at The Hawthorns. He made 149 appearances, including 19 as a substitute, scoring 22 times.
Head coach Roberto Di Matteo said: "I would like to thank Robert for his contribution and professionalism and wish him well for the World Cup and his future."
