Wolves boss Gary O’Neil admitted he may face further disciplinary action after confronting referee Tony Harrington following his side’s 2-1 Premier League defeat to West Ham at Molineux.

Wolves were angered when Maximilian Kilman’s goal in the ninth minute of stoppage time was disallowed, something O’Neil described as “possibly the worst decision I’ve ever seen”.

VAR Darren England advised Harrington to check the monitor as Wolves substitute Tawanda Chirewa was stood in front of Lukasz Fabianski in an offside position and deemed to be impeding the West Ham goalkeeper.

Wolves’ protests led to a flurry of yellow cards for those on O’Neil’s bench, and the manager said he walked towards the tunnel because he was aware he is one yellow card away from a touchline ban.

But O’Neil’s attempts to speak to Harrington after the game may yet lead to further problems.

“Unfortunately I wasn’t able to control my emotions and my feelings,” O’Neil said. “I was in with the referee and it didn’t go too well so I haven’t had an explanation.

“But the explanation is irrelevant anyway because everyone I’ve spoken to, David Moyes, Fabianski, they all can’t believe it’s been given for offside. It’s a terrible decision.”

O’Neil said Harrington shut down their conversation “probably because of the way I asked”, adding that he was “in a fairly bad mood” when he went to the referee’s room.

“I don’t know if it will be reported,” O’Neil added. “If I get told off, so be it. I’ve been told off many times before. I will apologise if I’ve stepped over the line but I can only react on how I feel at that moment.”

West Ham came from behind to win with James Ward-Prowse scoring directly from a corner after Lucas Paqueta’s penalty cancelled out a first-half spot-kick from Pablo Sarabia.

Moyes expressed sympathy for O’Neil but said any player stood where Chirewa had was at risk of being penalised for offside.

Asked if his side had got away with a decision, the Scot said: “I think I’m probably the last man at the moment to say you’re getting away with one. We’ve had so many poor decisions it is unbelievable in recent weeks.

“When I’ve looked at it again, the boy’s definitely standing in front of the goalkeeper…and if that player is not going to try to get back onside then there’s a chance you’ll be called offside.

“But I have to say I felt for Gary because the way I’ve felt the last 2-3 weeks with the decisions we’ve had, I’ve been sitting in a dark room for a week.”

Wolves have disputed several refereeing decisions throughout the season, and O’Neil said his players felt they had been disrespected.

“The players are unbelievably frustrated with the decision-making and officiating,” he said.

“They had a discussion as a group, they don’t feel like they’re being respected by the officials and I’ve talked them down a couple of times from figuring out what they want to do about that.

“I can’t expect them not to this time, I understand how they feel about it, and whatever they decide to do about it is up to them.”

Wolves had deservedly led at the break, but West Ham improved massively after the half-time introduction of Michail Antonio and Ben Johnson.

“I think the two teams changed shirts at half-time,” Moyes said.

But the win may have come at a cost with Jarrod Bowen limping off as Thursday’s Europa League match away to Bayer Leverkusen looms.

“He’s had a knee into his hip, or into his back,” Moyes said. “It’s not a twist but he’s really stiff. I’ve had one or two of those myself and they don’t go away too quickly so we need to hope it doesn’t linger with him.”
