Jose Mourinho's managerial career has been littered with success both domestically and in European competition but on Saturday, he hit one of his lowest points.
After a bright start to the campaign, the Special One's Manchester United side crashed and burned against Huddersfield, losing 2-1 at the John Smiths stadium.
Aaron Mooy and Laurent Depoitre scored the goals to condemn the Red Devils to their first defeat of the season and it was their second poor performance in the space of seven days.
In the 0-0 draw against bitter rivals Liverpool they were bad but against the Terriers, they were dreadful.
Even the serial moaner that is Mourinho couldn't fathom any excuses for the downright awful display from the majority of his players.
Only Romelu Lukaku and Marcus Rashford - who combined for United's goal - could have come out of the game with any dignity left.
The likes of Ander Herrera, Victor Lindelof, Juan Mata and Anthony Martial were simply woeful and in the dressing room at half-time, Mourinho made his feelings known.
The hairdryer treatment was administered, with Martial and Mata being hauled off at the break.
But, it turns out Mourinho's rage continued after the full-time whistle and he had some very, very harsh comments for Martial.
MOURINHO VENTS HIS RAGE AT MARTIAL
The French international looked disinterested during his spell on the pitch, with he and Herrera bearing the brunt of the manager's fury.
And, according to the Independent, the Portuguese boss was so livid with the former Monaco man that during his rant, he harshly commented that his performance was the exact reason he was so desperate to sign Inter Milan's Ivan Perisic in the summer.
Ouch, apply cold water to that burn.
Well, without having the Croatian to turn to, Mourinho is likely going to have to use English duo Jesse Lingard and Rashford in the coming weeks.
It will be a major shock if Martial is back in the starting XI to face Tottenham on Saturday lunchtime.
The same report also suggests that Mourinho was very concerned with the lack of focus in training before the game and expressly warned that a slip-up was likely.
Nevertheless, the nature of the loss still came as a bit of a shock, with United handing a huge initiative to Manchester City in the title race.
