Adam Matheson, who has signed on for his fourth season as senior coach, is backing his men to correct a "disappointing" seventh-place with more hard work in 2020.

The fourth-year coach said "unfinished business" motivated his decision to re-sign with the Walter Oval-based club.

"We were a little disappointed (with the season) so there's certainly some unfinished business from not only myself, but the playing group," Matheson said.

"(We need to improve) our commitment towards training because success comes from hard work.

"We want to have a more consistent pre-season and give ourselves a bigger base to work off going into the season itself."

Matheson backed Rovers' youngsters to seize more senior opportunities and flagged the club's midfield as its greatest strength.

He said tall targets would be a welcome addition to his side.

"We probably feel on the ball is one of our strengths. We'd like to pick up key position players because we want to be able to kick winning scores against top teams," he said.

"We want them at the other end as well because the more (goals) you stop, the less you have to score.

"We've had a lot of our premiership juniors back at the club in recent years and we'll hoepfully land a few of our key targets in the off season.

"That will help the development of our young players."

The Timboon Demons premiership coach said more consistency was also a goal across seniors and reserves.

"We'd like a bit more depth. Our reserves won the flag (in 2018) and we used 62 or 63 players through the reserves this year," Matheson said.

South Rovers football coordinator Matthew Wood said Matheson's signature was a boon for the club.

"He's done exceptionally well to develop our players so far," Wood said.

The Lions have opened applications for under 18, under 15 and under 12 coaching positions.
