COLLINGWOOD defender Leon Davis has declared he is no certainty to play next season, despite being in All-Australian form this year.

Davis, who has benefited from shifting from the forward line to half-back, told 3AW he was still mulling over his future.

Watch the CTV highlights from Friday night.

"Not necessarily [will I play on next season]. It's something I'll sit down and have a think about at the end of the year, but definitely enjoying my footy at the moment," Davis said.

Davis' pinpoint kicking skills have been a key factor in Collingwood's impressive season that sees it perched on top of the AFL ladder.

"I pride myself on my execution, so whenever I make mistakes I'm probably the hardest bloke on myself," Davis said.

"[I work hard on my kicking] so hopefully I can improve."

It was a different story last year when Davis was dropped for the Grand Final replay against St Kilda.

"It cut pretty deep, but I couldn't sit back and show my disappointment because it's a team game," Davis said.

"I got over it pretty quickly, and I just thought of the team and wanted to be upbeat and lift the boys up a bit."

While the 30-year-old is in career best form, he revealed the pull of family in Perth was a major factor in determining his future at Collingwood.

"I've got nieces and nephews getting older back home," Davis said.

"And of course I miss my family as well, but I suppose I'll have to have a think about it, and weigh it up and think about it in a serious context."

Davis is proud of his indigenous heritage, and has played a major role in mentoring boom Collingwood recruit Andrew Krakouer.

Krakouer has been a solid contributor for Collingwood this season after serving 32 months in prison for assault.

Davis said he and Krakouer shared a special bond.

"He's come back from obviously being in jail which was a pretty bad time in his life," he said.

"He's been a great mate of mine for a good 10 years-plus, so I kept in contact with him and tried to be there for him.

"For him to playing footy, alongside myself, is something I cherish each week and I try to push him to work hard."
