Ole Gunnar Solskjaer's men returned to English top-flight action with a trip to the King Power Stadium in the East Midlands. Going into the game, the Reds had a 29-game unbeaten streak away from home but, unfortunately, that was ended by the fired-up Foxes.
It started brightly for United, however, as Mason Greenwood fired us ahead with a stupendous strike in off the inside of a post, midway through the first-half, before Youri Tielemans also found the top corner, past David De Gea, to equalise for Leicester before the break.
After the interval, Caglar Soyuncu edged the Foxes ahead in the 78th minute with what was the start of a late goalfest.
