He insists new boss Harry Redknapp has already made them tougher to beat, with their narrow 1-0 defeat at Newcastle the first of his five-game reign.
“I think it's a surprise to most people in football that QPR are where they are,” he told the Albion website. “They made a significant investment during the summer in a number of players.
“But Harry has gone in there and they managed to get their first win. We are playing them on the back of that first home win.
“They lost narrowly at Newcastle, which is understandable because it’s a difficult place to go.
“They will be buoyed by the fact they won their previous home game.
“We will need to be at our best to get anything out of the game."
