Jadon Sancho's strike secured a third straight win for the Red Devils as Erik ten Hag's revolution continues to gather pace. The England international rounded Danny Ward in the first half to leave Leicester rock bottom and move Manchester United up to fifth ahead of Sunday's meeting with leaders Arsenal.
More than any point over the past year, they appear ready to challenge a top-tier Premier League opponent.
It was the first time Manchester United have won three consecutive games in the division since December 2021, which points to the improvement made under their new manager.
After humbling defeats to Brighton and Brentford in their opening two games of the season, Ten Hag has overseen a remarkable turnaround that has lifted the clouds that hung over the club.
Arsenal, who have a 100 per cent record this term, will be a major test of just how far Manchester United have come, but this was another game to suggest they are moving in the right direction.
