Youssouf Mulumbu pens new West Brom deal
The Democratic of Congo midfielder, who made 46 appearances last term, has signed a new two-year deal with the Baggies.
Earlier this week Graham Dorrans put pen to paper on a long-term contract.
And boss Roberto Di Matteo said: "I'm delighted that another of our talented young players has committed his long-term future to the club.
"Youssouf was one of about five players who played in the majority of our games last season and he played a major role in our success.
"The great thing about Youssouf is that he's a very humble guy who wants to learn.
"He's also going to get better and better because he is still young."
