The Red Devils missed out on continental football for the first time since 2014-15 after a dismal campaign last term and the midfielder says a return is paramount for the club in the upcoming season.
Mount said: "We obviously want to be back in Europe.
"I think that is a massive, massive thing for the club. I think that's the focus.
"We know how difficult that is now in the Premier League. There's so many teams that are obviously investing and playing very good football at the moment."
United endured their worst season for 50 years last term but Mount insists that the team have consigned it to the past as they begin a first full campaign under Ruben Amorim's management.
He said: "From day one of pre-season, it's about standards and details within training, obviously on the pitch and off the pitch and really focusing on us as a group and what we need to do to be better and to perform.
"[Amorim] is massive on details, the small improvements on the pitch or off the pitch and he's been really, really big on that.
"As a group, we know what we need to do in those areas and just trying to really improve that as a group because we need to be performing to the best of our ability.
"We haven't done loads of analysing of last season. We looked at a few areas that we can improve on but this is a new season.
"It's a new season for us and it's like wiping the slate clean. Coming into this season with a different kind of attitude and a feeling about it. We're ready to go."
