Skysports.com understands West Brom have signed Youssouf Mulumbu on a permanent basis after a successful loan spell.
Mulumbu joined West Brom on loan from Paris Saint Germain during the January transfer window and he impressed at the Hawthorns despite the club's relegation from the Premier League.
West Brom were keen to make Mulumbu's move permanent and new Baggies boss Roberto Di Matteo has acted to secure the Frenchman.
Mulumbu's agent, Doug Pingisi, has confirmed the defensive midfielder has agreed a two-year deal with the option of a further 12 months.
"Youssouf has signed for West Brom this morning," Pingisi told skysports.com.
"He has agreed a two-year deal plus another year.
"He is happy to sign for West Brom and is excited about working with Roberto Di Matteo."
