Olsson: Mulumbu massive for West Brom
The defensive midfielder has been outstanding for the Baggies.
Olsson told the Birmingham Mail: “He’s a massive player for us.
“He’s been putting in great performances ever since he came to this club.
“He’s a top guy, a funny guy and we’re happy with the way he’s been playing for us. For a centre-midfielder to be playing like that makes it easier for us.
“That’s what we lacked last time we were in the Premier League.
“We had good players in midfield but no-one really covering us."
