The call to “be sacked” wasn’t the only one that angry Wolves fans directed at their manager. However, it was one of the most printable.
In fact, the Wolves support rubbed salt into O'Neil's wounds by singing about former manager Nuno Espirito Santo, who is now in charge at Nottingham Forest.
Wolves finished 14th in O'Neil's first season last season, 20 points above the Premier League relegation zone, but it felt like the tide was turning against the manager, losing fan support and a Night from which he may not recover.
Defender Craig Dawson scored two own goals as Wolves allowed a Toffees side that had not scored since October 26 – a run of five games – to score four goals.
Wolves travel to West Ham, their own manager, on Monday Julen Lopetegui – previously of course in charge at Molineux – has real question marks about his future.
If both coaches survive by then, the game will no doubt be cruelly referred to as “El Sackico.”
O'Neil said: “I understand how difficult this role is because I know every single detail of this football club and the dressing room, but this is my job that I signed up for and what I have to do.”
“I will continue to take my share of responsibility for where we are at this moment. Whatever the fans may think about me and my team, there is definitely no one who works harder to help their football club than me.”
“I’m going to keep going until someone tells me not to.”
