AFL great Matthew Lloyd believes the AFL mid-season bye could be "movement time" for Carlton's Michael Voss as the spotlight on the beleaguered coach intensifies.

Amid questions over his coaching future, Voss was backed by Blues bosses last August to see out at least the final year of his contract in 2026.

But the 50-year-old faces an increasingly difficult task to reverse his team's fortunes after another horror second-half fade-out in the loss to St Kilda last round.

Carlton (1-7) are on a six-match losing streak ahead of a daunting interstate trip to face reigning premiers Brisbane on Friday night.

After that, the Blues take on the Western Bulldogs, Port Adelaide (away), Geelong and Essendon leading into their bye.

"It will be movement time then," Bombers goal-kicking legend Lloyd said on AFL.com.au.

"You just wonder if another club goes or another club's considering (changing their coach), Carlton will have to make their move.

"I feel like it's been a wasted year at Carlton though.

"With the moves they made and losing the key players they did - (Charlie) Curnow, (Tom) De Koning, (Jack) Silvagni - he (Voss) never really stood a chance."

Carlton have made their worst start to a season since a 1-10 opening to the 2019 campaign, which cost Brendon Bolton his job as coach.

Voss was questioned on his future after the St Kilda defeat, but said he wouldn't "speculate" on his own position as coach.

"I will go home, I will have a look at the game, review it and I'll turn up on Monday," Voss said.

"I'll be really clear on what we need to be able to get after, and then we dive into the week, and we find those marginal things to be able to get better next week.

"What circles around it is not for me to speculate on. What we will do is get after what need to be able to get better at."

Carlton's on-field leaders have also been in the gun, with Lloyd raising concerns over captain Patrick Cripps' ability to keep up with the increasing speed of the game this season.

Cripps had just 14 disposals and two clearances against St Kilda, who torched the Blues' midfield in a match-winning blitz during the third quarter.

But the two-time Brownlow medallist's sub-par performance came just one week after he was one of Carlton's best with 31 touches and 11 clearances in the loss to Fremantle.

"The game evolves so quickly and so fast ... he gets caught and he probably tries to do too much at times," Lloyd said.

"George Hewett has lost his spot in the side because they can't carry Cripps and Hewett in the same team.

"The game has moved to Shai Bolton and (Kysiah) Pickett and Hayden Young and all these guys ... and he just doesn't have that explosive power.

"It's worrying signs for him and Carlton right now."
