Albion had gone three Premier League fixtures without scoring before Gareth McAuley netted in injury-time to give them a share of the points at Craven Cottage on Saturday.
"We had to wait a long time for our first goal of the season but now it's arrived, hopefully the floodgates will open," he said.
"Victor played last week at Craven Cottage and as you saw, he's big, strong and powerful and can hold the ball up well for us. That's something we didn't have in the team going into the season.
"Stephane is quick and lively, he's direct and likes to take people on, he's a dribbler and an entertainer and hopefully he gets many chances here to entertain the crowd.
"All the signings over the summer have intensified and boosted the squad. Training has been good over the last couple of weeks and hopefully we'll start to see results on the pitch."
He added: "I'm not where I want to be. I want to be further up the league and have more points and scoring more goals. But I think we're moving in the right direction."
19th-placed West Brom will be looking to add to McAuley's goal when they host bottom of the table Sunderland on Saturday.
