Carlton football boss Brad Lloyd has conceded his and coach Michael Voss’ futures at the club are uncertain just hours after graffiti was sprayed across Princes Park calling for his sacking.

The graffiti, sprayed on the wall at IKON Park overnight before being washed off Friday morning, called for the Blues’ board to be sacked. It also singled out senior football department figures Lloyd and list boss Nick Austin, but said Voss should survive.

Former Blues spearhead Brendan Fevola on Friday called for a board cleanout.

Fevola initially backed the coach but then suggested Voss might have lost the players, judging by their lacklustre performance against Port Adelaide on Thursday night.

“The board needs to go. I’ve been saying that for ages... Get new people in, get old Carlton people in. Blokes like [1995 premiership player] Fraser Brown who would be amazing on the board,” Fevola said on Fox FM.

“Everyone is saying, ‘sack Vossy, Vossy needs to go’, and I’m like, ‘No, I don’t think that’s the go.’

“It gets to a point where you go, ‘I don’t think the players are playing for you, mate.’ If you’re playing for a coach, you don’t put up what you put up in that first half.”

Speaking to reporters as the team arrived at Melbourne Airport on Friday, Lloyd said he was “unsure” if he and Voss would be at the helm of the club in 2026.

“Unsure about that. We’ll just keep at it, keep going to work. [It’s] for others to judge that,” Lloyd said.

But Lloyd backed Voss and the board in the face of mounting public pressure and dismissed “toxic” fan behaviour.

The graffiti was washed off on Friday morning.

Someone, presumably a furious Carlton fan, scribbled graffiti at the Blues’ Princes Park headquarters before dawn on Friday calling for change at the club.

“I understand the disappointment, that’s for sure. It just depends on how you conduct yourself in that sort of thing,” Lloyd said.

“There’s behaviours that can work towards getting better outcomes for the club, and there’s probably toxic behaviours as well that don’t help anyone.”

Lloyd said Voss, who declined to answer questions when he arrived at Melbourne Airport on Friday, was hurting over the team’s form, but “holding up”.

The general manager of football said the club would need to stick together and not crumble under the scrutiny.

“Staying connected, making a safe environment for players to come in, do their work ... So just getting to work together, not fracturing,” would be the plan, he said.

Asked if more performances like Thursday night’s 50-point loss would force players, including Tom De Koning – who is considering a huge offer to cross to St Kilda at the end of the season – out, Lloyd said players were smart and could look to the future.

De Koning’s decision was also on the minds of the vandals. They wrote: “TDK yes or no?”

Incoming CEO Graham Wright will be the key decision-maker in assessing the Blues’ season, which is teetering with the team sitting 11th on the ladder with six wins and nine losses.

Last week pokies king and Blues financial backer Bruce Mathieson called for a complete overhaul of the club’s list, telling this masthead Carlton “haven’t got a good player under 25”.

Defender Nick Haynes’ message to his underperforming Carlton teammates on Thursday night was simple: shape up or ship out.

The veteran defender believes it’s up to the players – himself included – to execute Voss’ gameplan better and for longer.

“We’ve played some good quarters this year, which shows the system works,” Haynes said. “When we do, it looks exciting.

“But we haven’t been able to play that system for long enough; for four full quarters. We definitely take onus for that and it will be our goal next week.

“And if blokes don’t do it, we’ve got plenty of young guys coming through the twos who will play the system we want.”

Carlton have spent big to build a seasoned squad for the ‘now’, but the results continue to disappoint.

Retired great Lance Franklin said during the week he doesn’t expect Voss to see out the season, suggesting change “needs to happen, and it needs to happen ASAP”.

“You can’t target the coach on our fundamentals and consistency,” said Haynes.

“It’s on us players to execute that … Our goal now is to play the system we’re after for four quarters.”

Michael Voss’ position as senior coach of the Blues is under increased scrutiny.

Voss didn’t absolve himself or the players of blame after Carlton conceded the first nine goals against Port.

“It’s a collective accountability – there’s no separating groups here,” he said. “We always look at ourselves [coaches] first, then impart some of the things we need to in front of the players and ask them to play to the standard as well.

“We’ll look at it thoroughly and see what we need to correct.”

With the wolves circling, Voss insists he’s still the right man for the job.

“That was very unlike us, the way we turned up,” said Voss, whose coaching record now sits at 88-105-2.

“When you look at our body of work, there’s been a genuine shift in our numbers – and in a really good way ... That doesn’t leave me in any doubt whatsoever about what we’re trying to create here.”
