The Trotters are currently 18th in the Premier League table having won their last league outing against Everton earlier this month.
"For our part, we are under no illusions of how difficult our task will be, but having said that, we are in a decent run of form and the players are playing well," Coyle told the club's official website.
"We are passing and moving the ball, so we go there with a belief that we can be really positive, be brave in possession and get points from the game.
"All I want is for the players to go out there, give their very best and more often than not when you do that you will get results to go with it."
Bolton lost 5-0 to United in the reverse fixture at the Reebok Stadium earlier this season.
