Ridgewell has been impressed by his new team-mate, who crowned another outstanding display against Rovers with his fifth Albion goal of the campaign.
"I wasn't here when he left on loan, but Marco has been fantastic since I signed," the defender told the WBA website.
"He holds the ball up and bosses centre-backs.
"That's what you want from a centre-forward.
"He's been great for us and he's a really difficult player to mark.
"He's a real unsung hero, contesting every ball we play to him and holding it up."
