New St Kilda recruit Brad Crouch has opened up on his final few years at Adelaide, stating he now needs a clean slate after a "frustrating" ending to his career at West Lakes.

Crouch, 27, departed the 18th-placed Crows at the conclusion of the 2020 season, exercising his free agency rights and joining St Kilda on a reported four-year, $700-per-season deal.

The hard-nosed onballer was a key member of Adelaide's 2017 Grand Final side, where the Crows fell one step short of premiership success as Richmond were victorious with an eight-goal advantage.

Since the defeat, the Crows have won just 25 of 61 matches and finishing no higher than 11th, with Crouch tellingย SENย he was keen on a new beginning.

โ€œI definitely did (need a fresh start),โ€ Crouch told SEN Breakfast.

โ€œI probably felt it for a couple of years while I was over in Adelaide.

โ€œI donโ€™t know whether I was getting run down in the same environment, I think the way that we were playing at different times late last year was a bit frustrating.

โ€œFor me, I want to get back to playing good finals football again and being in a decent team."

Despite losing several key figures since 2017, Crouch believes the club held enough manpower to deliver in 2020 and should have won more than just the three matches.

โ€œIt was hard to deal with because we still felt we had a lot of the personnel around,โ€ Crouch said.

โ€œWe lost five or six key personnel but at the same time we were still under performing in comparison to what sort of talent we had on our list.

โ€œIt was definitely frustrating but itโ€™s refreshing for me now to go and have an opportunity somewhere else.โ€

Crouch will return to face his former club when the Saints host the Crows in Round 13.
