West Coast coach Adam Simpson says there are no excuses this year for Jack Redden and Lewis Jetta this season, after disappointing first seasons at the club.

Jetta was dropped on three separate occasions by West Coast as he struggled for form throughout 2016 after his much publicised move from the Sydney Swans.

Redden joined the Eagles from the Lions during the 2015 trade period and had a difficult season, largely to due to several niggling injuries. He averaged just 16 disposals in 15 games.

But Simpson says he is expecting a big season from both players.

"They've both come back with a really good attitude, they've done extra work and they've had full pre-seasons," Simpson told radio station 6PR.

"So there's absolutely no excuses at the moment that I can see they would have in regards to the prep they've had.

"They've both been in our top 10 in terms of training and turning up each session, they haven't missed a beat โ€ฆ but the proof will be in the pudding once we start playing."

The Eagles' pre-season campaign gets under way on February 18 against Greater Western Sydney in Narrandera.
