West Coast coach Adam Simpson admits he’ll feel a tad worried if Collingwood select star midfielder Adam Treloar for Saturday night’s qualifying final at Optus Stadium.

Treloar hasn’t played since injuring both hamstrings during the Magpies’ round 14 win over Carlton.

The 25-year-old has returned to full training and is pushing for an AFL recall this week.

Collingwood coach Nathan Buckley has hinted he’s unlikely to select Treloar against the Eagles.

But if Buckley ends up rolling the dice on Treloar, West Coast would definitely sit up and take notice.

“He’s an A-grade midfielder,” Simpson said of Treloar, who’s averaged 31 disposals and five clearances a game this season.

“He breaks the lines and he hits the scoreboard so there’s definitely some worries if he plays.”

Simpson said he wouldn’t devote too much of his planning on a single player.

Instead, it’s Collingwood’s system as a whole he would focused on.

Collingwood’s defence has been plagued by injuries this year but Simpson doesn’t see it as a weak point.

“We went through that in 2015 – we lost Mitch Brown and Eric Mackenzie through reconstructions and we had to play a different way, and we found a way,” Simpson said.

“I see Collingwood very similar how they’ve gone about it. It’s based around their whole team, not just three or four individuals. I don’t see that changing.”

Collingwood’s defence will be boosted by the return of Jeremy Howe (thigh), while Tyson Goldsack is also pushing for a return after recovering from a knee reconstruction.

Darcy Moore (hamstring) isn’t expected to be ready for Collingwood’s first final.

West Coast will welcome back Josh Kennedy (shin) and Lewis Jetta (calf), meaning Simpson has some tough selection decisions to make.

Two-game swingman Oscar Allen appears the most vulnerable, while veteran defender Will Schofield could also be on the chopping block.

Simpson held a team selection meeting on Monday and will hold more meetings on Wednesday and Thursday to finalise his team.
