The England international is coming off the back of a 30-goal season where he was unstoppable at times for Erik ten Hag's side.
However, Rashford has been unable to keep that form up and he is now facing criticism for his performances on the pitch and for his decisions off it.
Man United are in a tough place as a whole, but the 26-year-old's rut seems to be playing a big part in his side's lack of success this season.
What is Rashford's record for Man United this season?
Rashford has only scored one goal in 14 games in all competitions this season.
The forward's only goal this campaign came on September 3 as he netted in a 3-1 defeat away at Arsenal.

That means he has not scored in any competition for over two months for United.
To add to the drought, he has also struggled when it comes to goal involvement in general this campaign.

Away from goals, Rashford has only provided three assists across the Premier League, Champions League and Carabao Cup.
So in total, the Red Devils star has contributed to four goals across 14 games in which he has started all but one.

Rashford is yet to score in the Champions League this season, with United's group stage getting off to a nightmare start.
Ten Hag's men have lost two of their opening three games with qualification for the knockout rounds being thrown into doubt.
And it's also an important game for Rashford himself who is out to avoid a new record goal drought in the competition.
He has failed to score in any of his last seven Champions League games, last finding the net in October 2021 over two years ago.
If he blanks tonight, that will be his longest run of games in Europe that he has gone without a goal.
