The Red Devils are back in Europe’s top competition after winning the Europa League last season.
Jose Mourinho has already seen his side get off to a perfect start in the league with three wins out of three.
They have also scored ten goals without conceding any - with new striker Romelu Lukaku scoring three times.
The Special One will be hoping United can replicate their convincing league start in Europe.
Marcus Rashford, Joel Pereira, Scott McTominay and Axel Tuanzebe are all included on the B list as they were born after January 1, 1995.
