The 22-year-old striker played the full 90 in the 6-1 humiliation at home to Tottenham in their last fixture, and says his side have to produce a big performance at Newcastle on Saturday in the Premier League.
The Red Devils currently sit just outside of the relegation zone, after losing two of their opening three matches this season.

Marcus Rashford insists his side must bounce back at Newcastle on Saturday at St James’ Park
‘This is the opportunity to bounce back. Newcastle is a big game anyway, but this is an even bigger game because of the last result,’ Rashford told Sky Sports.
‘When you lose a game you want another one as soon as possible, you want to get that winning feeling back among the squad. Not only do we want to win, we want to win in a way that we can be proud of.
‘We want to work hard, not only for ourselves but for the guy on our left and right and do it as a team. We want to get three points together and then move onto the next game, that’s the way it’s got to be. It has to change, if it doesn’t then it is not what Manchester United are about.

The England forward, who has won widespread praise for championing charitable causes over the course of the year, also insists he welcomes the competition that new signing Edison Cavani will bring to Old Trafford.
‘Hopefully he comes in and scores goals, because he can definitely help us win games and points,’ he said.
‘He can be a massive player for us this season. To win two or three trophies in a season you need a squad, it’s not possible if you don’t have people who can score goals one week and the next week, it’s just not possible without three or four forwards in a team.
‘Growing up, United always had four or five forwards who could score goals at any time. The closer we get to that, the more strength we’ll have.’
