Darren Fletcher is refusing to panic despite Manchester United's poor start to the season under Louis van Gaal.
United's new manager stretched his winless streak to four matches on Saturday with a 0-0 draw at Burnley.
Midfielder Fletcher admits it has been a challenge to get to grips with the new 3-4-1-2 system implemented by van Gaal, but the Scot is sure everything will click into place eventually.
"It's mentally challenging but that has always been the case," the United vice-captain said when asked about the difficulties of adapting to a new formation.
"The players are learning a new system and developing ideas. It is going to make us better players in the long term.
"These things take time and we just have to keep believing in the manager's philosophy and ideas.
"There are other things that come into it, it's not just the system, but I am confident we will put things right."
United have spent upwards of £130million on four new players this summer and more deals are expected before the transfer window closes on Monday evening.
Fletcher believes the Dutchman has every right to make big changes given the club's seventh-place finish last term, and their performances so far this year.
"The manager was very straight and forward with the players and I think the players appreciated that," Fletcher said.
"You expect that after a disappointing season like last season."
