Carlton has brought back former Collingwood and North Melbourne forward Saverio Rocca to fix Levi Casboult's goal-kicking problems.

Rocca was brought to the Blues in 2015 to help Casboult, and it seemed to have a good effect as he finished the season with 24.12, the best accuracy of his career.

But the Blues decided not to renew Rocca's deal for 2016 and Casboult went on to finish the season with 18.18.

But fellow forward Matthew Wright said he is working hard to improve his much talked out kicking for goal.

"(Casboult's) working as hard as anyone to correct that," Wright said.

"If you look at the best goalkickers across the comp and you look at their statistics, I'm sure they'd like to be a lot better as well."

In his career with Collingwood and North Melbourne, Rocca booted 748 goals and 411 behinds, a conversion rate of 64.5%. He later became an NFL punter for Washington and Philadelphia.
