Green is convinced that the Royals will provide dangerous opposition as they aim to bounce back from their comprehensive defeat at Hillsborough.
"They will be looking to react," the shotstopper told QPR's official website. "They are always strong at home. It's another tough game but this league is full of them.
"We will be looking to build on this display against Derby. We've taken a step in the right direction and hopefully we can make another step. It has helped to re-instill what we already knew about this group."
QPR could move to the top of the Championship table if they win at the Madejski Stadium.
