Maguire, 27, is a booking away from his fifth in the league this term and if he collects a yellow card at Turf Moor he would be banned for the trip to Liverpool on Sunday.
“Harry is playing, definitely, that’s for sure,” Solskjaer stressed. “If he doesn’t wake up ill, you cannot only take three points and not put your eyes on games beyond this one.”
Edinson Cavani is pushing for a recall after missing the last three matches through suspension and the Uruguayan, who turns 34 next month, has not struggled with the intensity of the Premier League after spending seven years in Ligue 1 with Paris Saint-Germain.
Cavani has only started twice in the league but has scored a goal more than usual number nine Anthony Martial and the former PSG striker used his absence to rest up over the last fortnight.
“You can see he is a player who has looked after himself his whole career,” Solskjaer explained. “The little things like what he wants for lunch, what he wants for his pre-match meal, what he does before the games, what he does in the gym, how focused he is, how we are training. He doesn’t skip that.
“He knows he is here to improve and to get ready for the game, so those little things that you can see in players who have had careers and those habits I really like, and it was maybe the pre-match meal or lunch before a night game he wanted his meal in one specific way. He is a player who has been finding out what works for him throughout his career.”
United will go top of the Premier League if they collect just a point at Burnley before they face current leaders Liverpool at Anfield this weekend. United have not been at the summit in January since 2013 – the year they last won the title – and despite downplaying their title credentials Solskjaer is not about to rein in expectations, either.
Manchester United got back to winning ways with a low-key 1-0 victory over Watford in the FA Cup.
Scott McTominay’s early header was enough for the win at Old Trafford, as United booked their place in the hat for the fourth round.
United will now refocus on their league campaign with crucial games to come this week against Burnley and Liverpool.

“You don’t adjust your expectations because I have high expectations of these players,” Solskjaer added. “I expect them to go into every single game with a mental readiness to work hard for your team to win it and the results will come. As long as I can see that progress in that mentality and that we are ready for every game.
“If we go into every game with the right mentality and you don’t get results… I’m not saying that’s okay for them to have no excuses, because you can’t control results, and I feel that the group’s mentality is getting better.
“So of course that is the big thing for me: that we go into games with the right frame of mind. Sometimes results don’t go as expected but I am very happy with where we are mentally at the moment.”
