The West Brom keeper, hoping for a clean sheet at the Reebok, is impressed with the Trotters' form this season.
“Owen Coyle has got them playing a mixture of styles. They’ve still got a bit of old Bolton about them with long throws and big Kevin Davies holding the ball up.
“But they have also started popping the ball around and playing good football, so they’ve got all the ingredients to be a good side.
“A lot of people are surprised, but I know a lot of the players here aren’t too surprised because we know what a tough game they gave us when they came here.
“I think when Owen Coyle went in there he revitalised everyone and he has obviously got his thoughts across this season, which is why they are doing so well.”
