The veteran French striker recently joined the Baggies on a one-year deal and goalkeeper Foster is looking to see plenty of action up the other end of the pitch from the former Arsenal, Chelsea and Manchester City ace.
"Nicolas seems a really lovely lad," he told the club's official website. "He's going to be a fantastic addition to the squad.
"We're all looking forward to seeing him in action. I really want to see his butterfly celebration too. I always remember seeing him do that when he scored goals at Chelsea. I want to see him do it plenty of times this season!"
