The Chelsea striker, it has now been confirmed, will play out the season at the Albion.
"Rom's come into his own in the last month," Brunt told the WBA website. "The gaffer's been chopping and changing him and Shane and Rom has stepped up and grabbed a few goals for us.
"He's been consistently hitting the back of the net in the last few weeks even when we've not played that well, and the more he plays, the better he'll get.
"People forget he's only a young lad, he's still learning the game, but he's a real handful.
"He gets in good areas and hopefully he'll put more and more chances away as he gets more football."
