Solskjaer’s team had the perfect start though, with England sensation Mason Greenwood rifling United in front after 18 minutes.
However, on an afternoon where United struggled, Leicester came roaring back, as goals from Youri Tielemans and Caglar Soyuncu turned the game on its head.
Soyuncu’s goal sparked a crazy end to the game, with Marcus Rashford equalizing just minutes later, only for Jamie Vardy to pull Leicester back ahead 54 seconds later.
Patson Daka’s first goal for Leicester wrapped up the victory in the dying moments, and meant United has failed to win any of its last three Premier League games and only once in its last five games in all competitions.
The defeat ends United’s 29-game unbeaten run away from home — an English league record.
When asked about his side’s performance, the Norwegian called it a “bad day.”
