Jose Mourinho must have known that he was in for a bumpy ride when he took his Manchester United team back to his old Stamford Bridge stomping ground in the hope of booking a second Wembley appearance.
Not only are Chelsea storming ahead at the top of the Premier League table, but they also don't look as though they are showing any signs of slipping up in terms of their form.
Under Antonio Conte, the Blues seem to be going from strength to strength and United, who have been in good form themselves recently, were never going to be given an easy pass.
The game itself was hardly a classic, but things looked downhill for the Red Devils as soon as Ander Herrera was given his marching orders midway through the first half for two fouls on Chelsea star man Eden Hazard.
Friction on the sidelines between Mourinho and Conte threatened to boil over and the tie was settled when N'Golo Kante found the net in the second half.
Mourinho had already been the target of unsavoury chants from the home fans in the first period, who in unison decided to tell him to 'f*** off'. He responded to the chorus perfectly by gesturing them with three fingers to remind them that he won three titles for them on that very ground.
It was a brilliant way to hit back at some senseless abuse, despite his struggles there last season.
But the abuse didn't end there, as later on in the game the home fans began to chant 'Judas' at him for springing up at Old Trafford.
But this only provided him with the chance to hit back again in a way that only Mourinho could execute.
"They can call me what they want," Mourinho said per the Metro.
"I’m a professional, I defend my club and until the moment they [Chelsea] have a manager that wins four Premier League tittles [then] I am number one.
"When they have somebody that wins four I will become number two but until this moment ‘Judas’ is number one."
The funniest thing about the Chelsea fans calling him Judas, though, is that he didn't actually leave his post at Stamford Bridge to take over at Manchester United, he was sacked!
And they were much kinder to him last season as everything he tried failed to work and he'd obviously lost the dressing room.
Football fans can be fickle, but this is next level.
