Carlton has turned to a veteran forward and a new assistant coach to try to fix Levi Casboult's wayward goalkicking.

And Blues captain Marc Murphy says the club is deliberately minimising the number of people giving advice to Casboult.

Speaking to RSN radio on Tuesday, Murphy said the 26-year-old was being guided by new assistant coach Shane Watson and veteran teammate Andrew Walker, but Casboult was wary of taking advice from too many people.

"That's almost the problem sometimes, when it's not going well for you, you've got 15 people trying to tell you (what to do) … so we've spoken about limiting that," Murphy said. 

Despite Casboult's goalkicking woes, Murphy said his spot in the 22 wasn't in jeopardy.

"I think he'll certainly stay in the side. I think he is the answer for us," Murphy said.

"Levi is providing a huge contest for us and taking big grabs.

"But I think he's had a few off weeks, and it's been highlighted because you kick them out on the full or you don't go back from 30 or 40m out and kick them straight through the guts.

"But I reckon it will turn for him. He's working harder than anyone out there, big Levi, he's out there with his bag of balls when the boys aren't there and he's having a crack at trying to rectify it." 

Casboult, who booted 24.12 last season and has slotted 56.46 over his career, is often seen at training kicking at a post from 10m away. 

The Blues are averaging only 8.5 goals per game, with Murphy lamenting poor kicking in losses against Richmond, Gold Coast and from "30m out on not-too-hard angles" in the defeat to the Dogs.

The skipper also had a rough night against the Bulldogs, picking up just 10 touches after becoming sick during the match and being physically ill at half-time.

Murphy also needed staples for a cut to his head after a collision with Jordan Roughead's knee in the third quarter.


But the 28-year-old is likely to be fit to face Fremantle in a clash between 17th and 18th on the ladder at Domain Stadium on Sunday. 

"(My head's) not too bad. I didn't get any concussion, which is good," Murphy said.

"I was a little bit crook on Saturday night. I didn't have a bug going in, but during the game I got a bit crook and just made it out for the start of the third quarter, I had to run through the umpires' area to get out there.

"The body's feeling good now considering, but hopefully I've put that one behind me and I can play fresh on Sunday against Freo over there."
