Former Everton striker Gray has backed the Merseyside outfit to pick up all three points from the encounter at Goodison Park.
“This is my home banker for the weekend,” the former Scotland international wrote on Paddypower.com. “I’ve got to go for my old team and this could be nasty for the Baggies. Everton to win comfortably.”
A footnote added: “Andy’s bet: Everton 4-0 West Brom at 22/1.”
Everton are eighth in the Premier League table at the moment with 35 points from 25 matches.
The Merseyside outfit will head into the game against West Brom on the back of a 3-0 victory over Stoke City away from home at the Britannia Stadium.
Meanwhile, West Brom currently find themselves 14th in the Premier League table with 29 points from 25 games.
The Baggies are just six points above the relegation zone and are in real danger of getting relegated to the Championship at the end of the season.
Everton will be favourites to win against West Brom, and it should not come as a surprise if they do so handsomely.
