It's fair to say that Jose Mourinho didn't enjoy his return to Stamford Bridge as manager of Manchester United.
Mourinho's side were far from their best in west London and slumped to a humiliating 4-0 defeat.
The Blues ran riot against the Red Devils, taking the lead inside 30 seconds thanks to a strike from Spain winger Pedro.
Defender Gary Cahill doubled Chelsea's lead before the break, while goals from Eden Hazard and N'Golo Kante put Antonio Conte's side in dreamland.
Unsurprisingly, there was a great deal of reaction on social media to the game and one tweet, in particular, took centre stage.
That came from former Chelsea striker Eidur Gudjohnsen, who just couldn't resist a cheeky dig at Mourinho.
The Icelandic veteran, who racked up almost 200 appearances for the Blues between 2000 and 2006, trolled his former boss in style.

But what did Mourinho make of the contest? Well, the Portuguese tactician actually suggested that his side played well at Stamford Bridge.
The team played well, if we can delete the defensive mistakes we made," he told BBC Sport.
"Thibaut Courtois had more work than De Gea, their defenders had more work than my defenders. They are very dangerous in counter-attack, we knew that. I said if we score at the 2-1 game is different, that was not for us and they scored the third and fourth.
"Football matches start at 0-0, this match started 1-0. It is like giving Chelsea chance to play how they want. Everything went in their direction.
"I was focused on the game, calm with a bit of adrenaline, I didn't feel it different to any other big matches."
City on the horizon
Mourinho now has just three days to prepare his side for a clash against rivals Manchester City in the EPL Cup. After succumbing to defeat against City earlier on in the campaign, the United boss will be desperate to make amends at the Theatre of Dreams on Wednesday night.
