Ole Gunnar Solskjaer's side were thrashed 6-1 by Tottenham prior to the international break and will be itching to claim three points.
Just three days after that, United kick off their Champions League campaign against Paris St-Germain in a mighty clash.
And following on, a Premier League match-up against Chelsea – two sides vying to finish in the top four in a competitive year.
