United, currently sixth, are set for their second-worst finish of the Premier League era after Jose Mourinho gave up on the top-four to focus everything on winning the Europa League.
The Reds, whose worst Premier League finish was seventh in 2014 under David Moyes, are set for another big summer spend of more than £150million this summer, with striker Rashford confident they will push for the title.
“As a team we’ve developed and grown so much and we hadn’t been beaten in the league since October up until the Arsenal game,” said Rashford.

“So I think there have been many positives and they’re the things we have to take into next season. Then we just have to clean up on other stuff to make sure we are challenging for next season.”
United executive vice-chairman Ed Woodward hailed the progress made under Mourinho this season, despite the club’s failure to mount a title challenge.

Woodward said: “We’re approaching the end of a compelling season, our first with Jose as manager, and one in which I believe we’ve made tremendous progress, both on and off the pitch.”
United released their quarterly figures, with their net debt having risen by £17m to £366.3m, as a result of currency exchange rate issues caused by Brexit , while their total revenue for the full year is set to be between £560m-£570m.
