The Sun says Mourinho flung his coat to the floor as he tore into his flops.
The Old Trafford boss flipped in the dressing room for the first time since taking over after his side crashed 2-1.
And he made it clear players' futures were on the line if there is any repeat of the performance.
Mourinho publicly slaughtered his team claiming they lacked the same fight as newly-promoted Terriers.
He rapped: “The team that started with emotion, aggression, intensity, desire, that played the game of their lives was the team that won."
