The Scot watched the Eagles' 1-0 defeat to Arsenal last week and feels that they could easily have come away with a point.
"There are no easy games," the 50-year-old told reporters. "It is right to say 'no disrespect to Palace' because I watched them last week against Arsenal, and for 87 minutes they were right in the game.
"They certainly could have got a point. Arsenal's goalkeeper made a great save, and they hit the crossbar. It is not a game we take lightly - we respect Crystal Palace a lot.
"They are a team hungry for points and a group of players hungry to show they deserve to be in the Premier League. It is a game we are taking very seriously."
The Baggies are 12th in the Premier League, while Palace are bottom.
