Portsmouth manager Paul Cook says the wounds from last season's League Two play-off semi-final defeat by Plymouth have not yet completely healed.
Pompey and Argyle meet again on Saturday for the first time since the fiery tie in May, which Argyle won.
"The disappointment when you reflect back is that we didn't beat them when we were on top in the home leg," Cook told BBC South Today.
Pompey are currently fourth with Argyle top of the table after 12 games.
Peter Hartley's stoppage-time goal sent Argyle to Wembley as they squeezed through 3-2 on aggregate in May.
"This season's certainly not a clean slate," Cook added. "Those feelings at the end of a game like that should never leave you, they should drive you on to better things."
Defeat for Plymouth by AFC Wimbledon in the final denied Derek Adams' side promotion.
"Looking forward to the freshness of this season, both sides will be looking forward to achieving promotion," Cook said.
"Whether that be automatically or through the play-offs, what will be will be.
"But I want to be the team that's top of the league, not facing them. Once you play 12 games, the table starts to take shape.
"We've got a difficult game on our hands on Saturday, but I'm sure Plymouth will be thinking the same."
