Under-fire Manchester United manager Ole Gunnar Solskjaer understands mounting criticism and pressure but vowed not to "fall like a house of cards" after recent defeats.
The Red Devils reacted impressively following the chastening 6-1 home defeat to predecessor Jose Mourinho's Tottenham at the start of October, but things have gone awry in first week of November.
United fell to an embarrassing 2-1 loss to Champions League new boys Istanbul Basaksehir just days after putting in a flat performance in the 1-0 defeat at home to Arsenal.
Scrutiny has ratcheted up on Solskjaer ahead of Saturday's crunch trip to Everton, where they would have their lowest points tally after seven matches since 1989-90 should they fail to win.
Asked if he is as certain of being successful at United as he was when permanently appointed manager, Solskjaer said: "Yeah, why wouldn't I be?
"If I don't trust my beliefs and values and my staff's quality and the players' quality, who else should?"
Solskjaer added: "I don't look at one or two results and fall like a house of cards. But, yeah, setback definitely.
"I think there's been too much made of, say, not scoring against Arsenal and Chelsea because there's been more-or-less nothing in those two games.
"It's not too long ago we were the best thing since sliced bread when you beat Leipzig and PSG, so there's ups and downs in football and that's just the way it has to be.
"You've got to have that belief in yourself, belief in the players.
"The club has been very positive. They've shown me their character and the strong leadership, so I'm looking to Saturday lunchtime kick-off, which is another matter."
United have tended to react well to setbacks under Solskjaer and that will be crucial at Goodison Park ahead of the international break.
"You have to be mentally strong," the Norwegian said of dealing with the reaction.
"Of course there's demands on a Man United player and a coach and a manager.
"There's also an expectation because we are at the best and the biggest club in the world.
"You don't expect to have anything but criticism then, it's just how you deal with that, how you deal with that setback.
"From what I've seen from the boys, they've been very focused since we've come back, ready to give a response."
