Kevin Doyle says victory over QPR cannot be a one-off for Wolves.
He came off the bench against QPR on Saturday to set-up Matt Jarvis' equaliser and then scored the winner himself to give Wolves their first win in 10 games.
Doyle said: "We can't let that win be a one-off - that's the message we must all learn. Three points is good but won't mean anything if we carry on like we have been and getting nothing.
"The West Brom game is massive. We're at home and have to build on the QPR result."Wolves host the crunch Black Country derby clash with West Brom on Sunday.
