I'll have another go, and see if I can communicate my meaning this time.
The holidays thing is a red herring, and people are so pissed off with him that they'd use any stick to beat him with at the moment.
That any clearer?
Wish he goes fishing on holiday in his little yacht, catches the herring, then slips over it, meaning he cant do his day to day job as a manager, insurance will pay out, Koeman and Everton both win
replace him with a real German coach who could catch herrings all day.
we'd be feared just cos of his name.
