Chelsea stomped all over visitors Manchester United with a 4-0 pasting at Stamford Bridge.
The loss was even more bitter for Utd boss Jose Mourinho as he returned to Chelsea, the club that sacked him at the start of last season.
The Blues led after just 30 seconds when Pedro capitalised on slack defending to roll in.
Gary Cahill smashed in the second after United allowed Eden Hazard’s corner to bounce in their box.
United fell further behind when Hazard drilled in a precise 15-yard strike.
N’Golo Kante skipped around a static defence to slot in and seal victory as Chelsea moved within a point of Premier League leaders Manchester City.
This is Jose Mourinho’s heaviest Premier League defeat as a manager.
