MANCHESTER UNITED'S sponsors have been left annoyed that the club's star players have pulled out of events due to their on-field struggles, according to reports.
The Red Devils have lost more league games than they've won since Ole Gunnar Solskjaer became permanent manager and are currently seventh in the table.
There has also been growing unrest among United fans about the club's ownership and how it is run, culminating in a mob of supporters throwing flares at chief executive Ed Woodward's house last month.
And the Daily Mail claim the Red Devils' current plight has caused fears that players might be faced with difficult questions, leading some to withdraw from scheduled events.
The report adds that some sponsors also think that United are concerned about giving the wrong impression by having their stars complete commercial duties during this run of poor form.
According to their official website, the Old Trafford outfit are tied to more than 60 brands and organisations.
That includes a 24-strong list of global partners, highlighted by a £64 million-a-year shirt sponsor Chevrolet as well as £75 million-a-year kit maker Adidas and principal partner AON.
United's global sponsorships also rep official denim, tyres, betting, coffee, wine, spirits, financial trading and hotel partners.
Despite criticism over the performances on the pitch, executive vice-chairman Woodward has been credited for maintaining the club's massive worldwide commercial appeal.
Yet there are also growing concerns over the potential impact of Paul Pogba’s potential departure.
The French World Cup Winner, linked with moves to Real Madrid and Juventus, is one of the most high-profile footballers in the world.
Should United fail to reclaim Champions League football, club chiefs may not be able to attract a player who could replace Pogba's global stature.
The midfielder is under contract until 2021, although United have the option of extending his deal by 12 months.
