There will likely be no goals until Scholes is taken off. If he remains on then it will be a 0-0 draw. At least there's no Carrick; United would be losing right now. Chris Walters
The home side remain odds on (1/3) to claim a win here, but they'll be disappointed not to have broken QPR down, with the visitors' chances of a 0-0 draw rated at 9/2 with Sky Bet. United won both fixtures against the Hoops 2-0 last season, a scoreline which is now available at 3/1 this time around.
As much as Man United want to get back to their winning ways, QPR will also want to bring their losing streak to a halt. There will be a good fight in this game. I predict 3- 1 to Man United. Kofi Ghartey

You would be a fool to back QPR today. Ignore their failure to win this season, United want and need to get back to winning ways after Norwich. Strong line up from United. Intrigued as to why Valencia and Nani are both missing - unless I've missed something. Either way, you have to predict United to knock in at least 3. Personally, I'd predict a 5-1 home win, with a hat-trick from Wazza or RVP. Roger Clarke

Meanwhile, QPR skipper Park Ji-Sung misses the chance to face his former employers due to an ongoing knee issue, but Stephane Mbia is back after serving a three-match ban. Strikers Bobby Zamora (hip) and Andrew Johnson (knee) miss out, along with full-back Fabio, who cannot feature against his parent club.
United have been boosted by the return of Rooney after the England striker was passed fit following a bout of tonsillitis. Chris Smalling is also available having shrugged off a shoulder problem and takes up a spot on the bench, while fellow defender Jonny Evans starts in the heart of defence alongside Rio Ferdinand.
Manchester United are overwhelming favourites (1/6) to get three points here today, with QPR's chances rated at 14/1 as Mark Bowen and Eddie Niedzwieck take charge of the visitors at Old Trafford. We've had plenty of money on a 3-0 home win (6/1) for Ferguson's men, while Wayne Rooney has been a popular choice at 11/4 to open the scoring. Former Liverpool striker Djibril Cisse is 5/1 to score at any time, with Robin van Persie priced at 9/2 to score in the opening 10 minutes.
Working in United's favour is the recent sacking of manager Mark Hughes by the Hoops. The Welshman was shown the door at Loftus Road on Friday after he failed to pick up a single win in the first 12 games of the season. Harry Redknapp has since been named Hughes's successor, although the former Tottenham and Portsmouth boss won't be on the sidelines until next week.
A surprise 1-0 defeat for Sir Alex Ferguson's side at Norwich last weekend allowed rivals Manchester City to go top of the standings. But trailing City by just one point, and with the defending champions only in action at Chelsea on Sunday, the Red Devils can capitalise on the 24-hour advantage.
Good afternoon, I'm Devin Hermanus and I'll be taking you through all the action as Manchester United host Queen's Park Rangers at Old Trafford. Kick-off is scheduled for 1500 BST.
