Why wouldn't De Zerbi want it ? He'd be mad not too. A 5 year deal on mega bucks, that he'll probably get the end of the season if he takes Spurs down. He will get no blame," not his team," already down", "done his best" and "not enough time". Moves on and gets another top job. If he keeps Spurs up, hailed as "a miracle worker", probably a massive staying up bonus, massive transfer war chest, no Europe just concentrate on cup competition and try to qualify for Europe. It really is a no lose scenario there, he doesn't have to be great following the last saps.
Won’t get the blame if they go down and next season they’ll absolutely demolish the Championship and get about 100 points. Can see why Dyche was basically whoring himself out for the job and getting his media cronies to push his name out non-stop.
