Collingwood coach Nathan Buckley says Brayden Sier's omission from the side is due to getting the team balance right.

The 21-year old played a key role in the Pies' midfield in the back half of last season, averaging 19.5 possessions and 3.9 clearances across 12 games, including a 21-disposal effort in the Grand Final.

But Sier is yet to receive a senior opportunity this season despite Collingwood's star-studded midfield failing to fire in the opening three games.

โ€œWeโ€™re definitely looking to get the balance in our side. We need a certain amount of inside midfielders and you need the runners outside,โ€ Buckley toldย SEN Breakfast.

โ€œBrayden was clearly in our best mix towards the end of year and played some really good footy with lower game time. He was a 65 per cent midfielder and just gave us the capacity to thicken the soup.

"Heโ€™s had an okay pre-season, heโ€™s got some solid work in. Heโ€™s had a few little injury concerns over the last month or so but I think what Brayden is working out as we all discover at some stages of our career is that itโ€™s a tough caper. You need to keep finding ways to improve, you need to keep doing the work to get the rewards and there are form fluctuations as well.โ€

Buckley remained confident that Sier would get his chance at some stage.

โ€œWeโ€™ve got no fears that he has the talent to get back to where he was last year and beyond that,โ€ Buckley said.

โ€œHeโ€™s just a young man.โ€
