Eddie Betts has backed Sam Petrevski-Seton to crack the Carlton midfield next season despite rumours the Western Australian could be on his way home at the end of 2021.

Petrevski-Seton's time at Carlton is delicately poised with the Blues reportedly keen on bringing in Adam Cerra from Fremantle and the Dockers willing to bring Petrevski-Seton back home.

The former pick five has struggled over the last two seasons under David Teague with a move from the midfield to half back seemingly halting the progress of the silky Petrevski-Seton.

The retiring Eddie Betts believes there is still a place at the Blues for Petrevski-Seton despite reports he will depart Ikon Park.

Betts said that his teammate has been frustrated with a lack of midfield time under Teague but needed to get his tank right before making the step up to be a permanent part of the Carlton engine room.

โ€œWhen you look at Jacob (Weitering) and Sam (Walsh), their positions are set in stone,โ€ Betts said on Sportsday.

โ€œSamโ€™s (Walsh) always going to be in the midfield, Jacobโ€™s always going to be full-back.

โ€œI guess for Sam (Petrevski-Seton) heโ€™s been thrown around this year in a few different spots and I believe he really wants to play in the midfield.

โ€œHeโ€™s got to build his tank up a little bit because heโ€™s got the skills to use it. Heโ€™s playing in the midfield in the VFL and heโ€™s dominating, using his skills to hit targets and racking up 30 disposals.

Betts said that Petrevski-Seton has been frustrated with his constant changing of roles in the Carlton side but that it's up to the 23-year-old to take control over the next part of his career.

โ€œI guess with him heโ€™s been a little bit frustrated this year that he wanted to cement a spot in the side, but that wasnโ€™t happening because he was at half-back, in the midfield, came down forward to try a small forward role and it just wasnโ€™t clicking," Betts said.

โ€œI reckon he needs to cement his spot, but over this pre-season he needs to get his tank right and just say, โ€˜Listen, put me in the midfield, I deserve a spot in this midfieldโ€™, and just go from there.โ€

Tom Morris ofย Fox Footyย is reporting that Petrevski-Seton is likely to leave the Blues at the end of the season in pursuit of more consistent senior opportunities in the midfield.

Petrevski-Seton has not been homesick in his time at Carlton and loves it at the Blues but is keen to cement a spot as a midfielder at AFL level.

โ€œSam Petrevski-Seton, everyone really expects him to go home to Perth, not because he doesnโ€™t like playing at the Blues but because he wants more senior opportunities. Certainly Fremantle are in the running for him,โ€ Morris told Fox Sports Newsโ€™ย AFL Tonight.
