The stats behind Jose Mourinho's nightmare start to the season at Manchester United

The Portuguese suffered his heaviest Premier League defeat as a manager at his former club on Sunday as the Red Devils continued their disappointing start to the campaign.

Manchester United's humiliating 4-0 defeat to Chelsea has ensured Jose Mourinho's men have made one of their worst starts to the season in Premier Leage history.

Mou slams Conte for Chelsea celebrations

Only once before in 2014/15, under Louis van Gaal, has Man Utd collected fewer points (13) after the first nine games of a Premier League season than this campaign (14).

Sunday's thrashing by the Blues at Stamford Bridge was also Mourinho’s heaviest Premier League defeat as a manager. Only against Barcelona in Nov. 2010 did he lose by a greater margin in all competitions, a 5-0 defeat.

Chelsea has been an awkward opponent for Manchester United over the years and the last time Manchester United lost by four or more goals away from home in the Premier League was against Chelsea at Stamford Bridge in 1999 when the club was thrashed 5-0.

Indeed, the Blues have now gone eight league games without a loss against Manchester United having won four and drawn four, the club's best run against the Red Devils in their history.

Goal-scorer Eden Hazard also had reason to celebrate. The Belgium international has now equaled his goal tally from last season in the Premier League.

Hazard has four for the season in just nine games, while last season it took him 31 games to reach the same tally.
