The Red Devils have suffered their worst start to the season in 29 years after winning just three of their last seven matches in the EPL.
They were also forced to a goalless draw by Valencia in their Champions League match day two encounters at Old Trafford on Tuesday, October 2.
With their last result, United have gone four games without a win at Old Trafford in all competitions and are now tenth on the EPL table.
Jose Mourinho's men will hope to bounce back to winning ways when they host Newcastle United this weekend before the FIFA international break.
On return from the break, they travel to the Stamford Bridge to battle Chelsea - who are yet to lose any game in the English topflight this term.
They host Juventus in the first leg of their UEFA Champions League clash later this month after which they clash Man City in November.
However, the outcome of these matches will determine the future of the Portuguese tactician at the club.
Scholes's former United team-mate Rio Ferdinand also told BT Sport that Mourinho should take the ultimate responsibility for United's problems.
Former United defender Rio Ferdinand while reacting to the issues rocking the Red Devils said that: " There's not a work ethic.
"The attitude doesn't seem right. No one's said about not going out there to win - people want to win football matches .
"If you could win it easily you would. Football's not easy, you have to work hard. That's a basic trait of any footballer or any team to be successful they have to have .
"This team doesn't have that, and where does that come from? That comes from and is driven by one person at the top, the manager. It falls at his feet."
