Immediately after pouring his Shreddies into the bowl, he went to collect some milk only to come away empty handed.
The Special One was clearly angered by the 'witch-hunt' against his strict morning routine.
He said: "I won the title quite recently. I should have milk whenever I need it. I have done enough to deserve milk. Where's my milk? It's a witch-hunt.
"You guys (the media) would never let Arsene run out of milk. Have you ever considered even letting him run low? This is unfair against me, Manchester United and my poor, dry shreddies."
"It's a disgrace."
Mourinho was then seen to storm out of the pre-match press conference with what appeared to be an Alpen cereal bar tucked in his back pocket.
DISCLAIMER: In case this isn't obvious... this is a bit of fun.
