Robbie Savage says that Chelsea and Manchester City could embarrass Manchester United at the end of the month, when the Red Devils face off against the two favourites to win the title.
United have started the season in poor form, which their defence looking particularly vulnerable, and Savage believes that Chelsea and City could expose all Louis Van Gaal's side's current problems if they do not eradicate them quickly.
The Red Devils take on Chelsea on October 26th and their local rivals City on November 2nd and the BBC pundit believes that it could be a humiliating week for England's most successful club.
"His [Louis Van Gaal's] side play Chelsea and Manchester City in the space of seven days at the end of October," Savage wrote in his column for BBC Sport.
"They have to get things right at the back by then because, otherwise, they will be on the end of more embarrassing score lines."
United have won just once over the opening part of the campaign and much of the initial optimism that had been generated around Old Trafford after a promising pre-season has already evaporated.
The defensive issues that plagued their campaign last year have shown no signs of being rectified and they are already in a worrying slump of form.
Although United possess arguably the best forward line-up in the Premier League, their squad is unquestionably top-heavy and it doesn't seem a balanced formula to start winning games.
The Red Devils slumped to seventh place last year and, with the level of investment they have made, a similar finish is unthinkable, but unless things drastically improve it is set to be another season of struggle.
Savage believes that they have less the a month to eradicate their weaknesses or risk embarrassment and it is hard to disagree with his analysis, given the concerning start United have made.
