The challenge for John Mousinho’s side is to record three wins in a row for the first time this season.
But Marti Cifuentes’ side are a different prospect to the struggling side faced at Loftus Road, with 10 wins from 17 seeing the the Londoners charge away from relegation safety.
There are players returning to fitness like Kusini Yengi and hopefully Freddie Potts, though Callum Lang has been ruled out for the season.
Here’s how we think Mousinho will go, as he hunts down another win to ease relegation concerns.
