West Brom have exercised their option to turn Do-heon Kim's loan move into a permanent transfer, and he will join for £550,000 on June 1.The Korea international will complete a switch to The Hawthorns after Albion notified the midfielder's club Seongnam Ilhwa Chunma of their intentions.

The option was agreed when Kim joined the Baggies on loan until the end of last season on January 31 following an impressive training spell with the club the previous month.

The Premier League newcomers have agreed personal terms with the 25-year-old on a two-year contract, plus a further year's option in the club's favour.

"The four months he has already spent with us will have been a big benefit to him in terms of integrating with the squad and overcoming the language barrier," said West Brom boss Tony Mowbray. "I am now looking forward to working with Kim next season.

"His loan spell was all about settling into a new club and culture but he has got undoubted talent and he will have a more significant part to play next season."

Kim was limited to just one start and six substitute appearances last season. He made a vital contribution on the final day at QPR, coming off the bench to score his first goal for the club to help clinch the Championship title.
