Chelsea made Jose Mourinho's return to Stamford Bridge with Manchester United a day to forget as they thumped four goals past the hapless Red Devils.
Much was made of the Special One's return but he was largely ignored for the best part of 90 minutes.
He was told by some fans in the East Stand that he wasn't special anymore at 2-0 and then chants of 'You're getting sacked in the morning' when the Blues went 3-0 up.
However, at 4-0, Chelsea fans roused into a cheer of 'Jose Mourinho' that you couldn't help but feel was in sympathy to the twice-axed Blues boss.
It didn't take the home side long to get into gear as Pedro capitalised on slack defending from Chris Smalling to nip the ball in front of David De Gea, round the goalkeeper and slot home inside the first 30 seconds.
Just 20 minutes later it was 2-0 as United failed to deal with a corner and Gary Cahill found space at the back post to fire home.
David Luiz was lucky not to have handed Manchester United a lifeline in the closing stages of the first half with his late and high tackle on Marouane Fellaini earning him a yellow card, when it could have been red.
N'Golo Kante, who was everwhere for the Blues during the game helped set up the third just after the hour mark as he and Nemanja Matic linked up to play in Eden Hazard, who slotted the ball into the net.
And the Frenchman skipped past the shellshocked Red Devils defence to make it four 10 minutes later and complete the rout.
Zlatan Ibrahimovic had a chance for a consolation but Thibaut Courtois, who did everything he needed to do all game without much fuss, denied the Swede.
