QPR haven't beaten United at home since 1989, and Sky Bet punters are not convinced they can end that run as the large majority of the pre-game money has been placed on an away win at 8/15 on. With just eight goals scored at home this season, No on Both Teams to Score at evens seems a banker, but United To Win To Nil at 13/8 is a similar option with much better value.
United, meanwhile, go into the game on the back of a 16-game unbeaten run in all competitions, having registered their last defeat back in December against Romanian outfit Cluj in the Champions League. A win for Sir Alex Ferguson's side in the capital will see them go 15 points clear at the summit.
QPR have shown commendable resistance since Harry Redknapp took over the reigns from Mark Hughes in November, although they are still battling to stave off relegation. The R's had gone on a four-match unbeaten run in the league, before eventually succumbing to Swansea in the 4-1 away defeat a fortnight ago.
Good afternoon, I'm Devin Hermanus and I'll be taking you through all the action as Queen's Park Rangers host Manchester United at Loftus Road. Kick-off is scheduled for 1500 BST.
