The result at Old Trafford leaves United with 70 points from 35 matches, 10 behind City with three games left to play in the 2020-2021 campaign.
The title marks the latest landmark in Guardiola’s glittering career at the club. After joining City in 2016, Guardiola landed his first league title at the Etihad a season later, as he masterminded a superb campaign where the club finished with a league-record 100 points.
City retained their title the next season, as Guardiola’s men edged Liverpool in a thrilling title race, finishing on 98 points — a point ahead of Jurgen Klopp’s side. In addition to domestic league glory, Guardiola has also lifted the League Cup four times in a row, as well as the FA Cup in 2019.
Manchester City have three league games remaining, against Newcastle, Brighton and Everton, before attention will turn to the club’s first-ever Champions League final.
The club’s latest league title moves them on to seven in total, with Manchester United still out in front on 20.
