Not only was the Magpies star on the end of a drubbing at Everton which ended his team's Champions League hopes, but he also sparked fury at Goodison Park with his shocking behaviour towards a ball boy.
The midfielder was clearly frustrated as Newcastle had gone behind in the first half, and when the ball went out of play in the 25th minute he rudely snatched it from a ball boy, almost knocking him over in the process, and then appeared to raise his hand towards him in fury.
The crowd howled in disapproval at the Frenchman's actions, and referee Andre Marriner had a stern word with the player even if he somehow failed to hand out a yellow card. Cabaye did at least seek out the ball boy to apologise and give him a perfunctory hug - something which the youngster did not appear to appreciate at first, though he subsequently broke into a grin.
You'd have thought that Cabaye learned his lesson, but he had not: at the final whistle his angry words towards the Toffees' Australian star Tim Cahill sparked a fight which earned Cahill a red card for grabbing Cabaye by the throat.
Cabaye later apologised for his actions, claiming that it was "out of character" and "the result of frustration and disappointment, all in the heat of the moment."
But somehow we don't think he will be made to feel very welcome next time the Toon head back to Merseyside.
