Ed Woodward believes Manchester United are making "tremendous progress" under Jose Mourinho despite missing out on a place in the Premier League's top four.
Mourinho, who arrived last summer, has won the Community Shield and the EFL Cup and will lead his side in the Europa League final against Ajax next week as they look to seal Champions League qualification.
And executive vice-chairman Woodward said: "We're approaching the end of a compelling season -- our first with Jose Mourinho as manager and one which I believe we've made tremendous progress, both on and off the pitch.
"It has been an incredibly busy season which will see us play 64 matches, including an astonishing nine matches last month. This will be the second-busiest season in our history.
"In the league, we set a new club Premier League record with 25 matches unbeaten within a single season.
"We've won the FA Community Shield and the EFL Cup, and obviously we're delighted to have reached the final of the Europa League, the only major trophy we have never won."
Woodward, speaking on United's third quarter earnings conference call, suggested his positive appraisal was shared by fans, with season tickets for 2017-18 sold out more than three weeks earlier than ever before.
Plans are already afoot for next season, with signings targeted and a preseason tour organised in the United States.
It will include the first Manchester derby played on foreign soil in Houston, Texas.
"Visiting North America will give the team the best possible preparation for the new season, using top-class training facilities and playing at some great stadiums," Woodward added,
"Given all the records we've broken this year, we'll watch closely to see if we break our tour attendance record."
