Manchester United boss Louis van Gaal has reiterated his desire to keep David de Gea at Old Trafford.
QPR are interested in signing West Ham midfielder Mark Noble, Sky sources understand.
Sky Bet make Mark Hughes 5/6 to have left QPR by Monday morning after the Hoops' woeful start to the season hit a new low as they lost 3-1 at home to Southampton.
The 49-year-old headed into the weekend as the 6/4 joint favourite to be the first Premier League manager to go along with Saints boss Nigel Adkins, who has been pushed out to 12/1 following a first away league win this season.
A 12-match winless run has seen the Hoops cut from their pre-season price of 4/1 to 8/11 for relegation, while Harry Redknapp is rated as Hughes' most likely successor with QPR the1/4 favourites to be his next club.
Sky Bet Football Trader Chris Spicer said: "We expect the board to act with QPR slipping deeper into relegation trouble after a hopeless start to the campaign.
"Hughes is clearly not getting the best out of his expensively-assembled squad and Redknapp looks the perfect candidate for the job given the way he has turned around under-performing sides previously, with Tottenham the perfect example."
