LONDON: Chelsea scored two late goals against Southampton to top the Premier League table.
Elsewhere, Brighton drew 0-0 with Arsenal to end the Gunners' recent winning streak while Leeds earned their first league win of the season and Norwich avoided defeat for the first time.
United's 1-1 draw at Old Trafford continues an unimpressive run of home results including a League Cup defeat by West Ham and last week's shock Premier League loss at the hands of Aston Villa.
Chelsea ended a miserable week on a high, with Timo Werner and Ben Chilwell striking late in a 3-1 win against Southampton, who are still without a league victory this season.
The three points lifted the Stamford Bridge club to the top of the Premier League on 16 points, two clear of Liverpool, Manchester United and Everton.
Thomas Tuchel's side, tipped by many to win the Premier League in the early weeks of the season, were well beaten by Manchester City last week and lost to Juventus in the Champions League in midweek.
But they returned to winning ways in London on Saturday, helped by a second-half red card for Southampton midfielder James Ward-Prowse.
Trevoh Chalobah nodded Chelsea into an early lead but Ward-Prowse levelled from the penalty spot just after the hour mark before he was sent off in the 77th minute for a dangerous tackle on Jorginho after a VAR check.
Werner provided the decisive moment, sliding in from Cesar Azpilicueta's cross before Chilwell volleyed in from close range on 89 minutes to secure the victory.
"After two defeats we had to be careful that we didn't start being too sad or too worried because there was a chance to be on 16 points," Tuchel told the BBC.
"It was important to have a better performance than the last two games, that we sharpened our mindset so that we are not afraid to lose. It was nice to play the way we did and get a deserved win."
Mikel Arteta's Arsenal were bottom of the Premier League table after three matches before three consecutive wins lifted them to the comfort of mid-table.
But they were found it tough to break down high-flying Brighton in a soggy evening contest on England's south coast with the teams managing just four shots on target between them in the goalless stalemate.
Earlier, Leeds beat Watford 1-0 thanks to a first-half strike by Diego Llorente while Hwang Hee-chan struck twice as Wolves beat struggling Newcastle 2-1.
Norwich stopped the rot against Burnley after six straight league defeats but they remain rock bottom of the Premier League table with just a single point from seven games after a 0-0 draw.
