Solskjaer spoke up the Foxes' credentials while insisting that United can now not afford to drop behind Leicester, along with even alternative competitions including Arsenal, Chelsea and Tottenham.
"Leicester is always a tough game. It's a staff and a club that's wanting to drive for the top four I'm sure," he explained. "They have good players and an excellent manager, that's a proven top supervisor.
"Brendan's teams play great football and we will need to play well to deserve three things. We would like to receive the results. We are currently coming into a busy period we do not need to be supporting Chelsea or Tottenham or Arsenal.
When asked when Leicester are on precisely exactly the same amount as United today, Solskjaer responded:"I don't want to speak too much about Leicester.
"I find them as a great group but Man Utd is the largest and best club in the world. I'm sure like we do, they would like to enter the top four. It is a challenge that is fantastic and a test. For our players who wish to push closer to City and Liverpool, here's your chance."
Solskjaer verified that Martial and also Pogba will miss Saturday's trip of Leicester but both may make their recurrence once United face next week to West Ham United, live on Sky Sports Premier League.
Wan-Bissaka and lingard will face late fitness tests following the group originated with injuries per week from England duty.
"The treatment room has been busy and is," he explained. "We do not really know who is going to be available. Perhaps Aaron, maybe Jesse and that is it from those that had to pull out however I can not guarantee those two will be matched "
"Pogba will not be fit unless he has had a miraculous comeback overnight. He has not been ready to train at 100 per cent.
"We expect more can be ready for West Ham, Paul and Anthony are in this category. I think they'll be ready for then. I can not say over that."
Sky Sports' Gerard Brand
'Having taken just five points from their opening four matches, this aggravation could not have come at a worse moment for Manchester United.
'Solskjaer's overhaul of United in the summer focused on outgoings, a number of whom they can do with this particular weekend.
'Together with Pogba, Martial and Shaw outside, and Lingard and Wan-Bissaka doubtful, it is probably Nemanja Matic will line up with one of Andreas Pereira or Juan Mata and Scott McTominay.
'In right-back, possibly Timothy Fosu-Mensah or Axel Tuanzebe could insure Wan-Bissaka, with Ashley Young already covering Shaw about the left, and at the line, Marcus Rashford is very likely to be flanked one of Mason Greenwood or even Mata and by Daniel James.
'Only one of the replacements - Pereira - has played over 100 minutes this season from a 360. Although Matic has just 22 and Greenwood 47 Tuanzebe and fosu-Mensah have no moments.
'Against a Leicester side sitting and unbeaten, defeat here will depart United five things away from the top four before the initial week that is European, also with only one top-six opponent ticked off the fixture list.'
The United manager also resisted his desire David de Gea to stay outside this year at the club.
The Spaniard will be free to enter talks with clubs from overseas and will soon be out of contract at Old Trafford at the conclusion of the effort.
"I need David to remain here, he knows that. David is the best goalkeeper in the world.
"We've noticed that over the years. I hope I can make sure that he will finish his career at United in the highest level.
"There have been plenty of discussions and talks between David and the club and hopefully we can get it done."
