Paul Pogba insists Manchester United are “young and fresh” and have unwavering confidence in their ability to secure a top-four finish.
The Red Devils have spent almost the entire 2016-17 campaign on the fringes of the Champions League places.
They remain on the outside looking in at present, despite having pieced together a 25-match unbeaten run in the Premier League.
The £89 million midfielder told MUTV: "Of course, we have to believe.
"Obviously, we want to do it and we can. Of course we're strong enough, we are Manchester United and we can do this.
“To be in the top four, our mind has to go there, and we also want to win the Europa League.
“We have to keep our heads on the challenge and the big objective; we want to achieve the big goals, not the small ones. We're confident of that. We're young and fresh.”
United will head into a crunch clash with Arsenal coming off the back of a 1-0 victory away at Celta Vigo in the first leg of their Europa League semi-final.
Pogba is delighted to have seen momentum and confidence maintained in Spain, with the big games continuing to come thick and fast.
He added: "It was a good result for us against Celta, and a very important goal.
"We now need to focus on the second leg and have another big game coming up too, against Arsenal. We have to get our head into this game, and then we can think about the second leg.
"I feel good, but you have to be careful as well. It's not finished, we won 1-0 in Spain and the team did a good job, but we'll have to be focused for the next game.
“It's the objective for us, and it would be great to win the competition. As I said, we're not there yet, we have to keep going and be focused on the next game."
