Bayern Munich were eliminated by Paris Saint-Germain in last season's semi-final, losing 6-5 on aggregate despite Kane levelling the second leg in stoppage time, in a tie the striker felt could easily have gone the other way.
Speaking to TNT Sports, Kane reflected on the fine details that separated the sides.
"Last season, small details made the difference. We go into this season with the thought: this has to be our year," he said.
Kane's individual output last term was extraordinary regardless of the disappointment, with the England captain contributing 73 goals across club and country combined, form that earned him a Golden Boot award. Even so, the 32-year-old made clear that personal accolades mean little without the trophies to match, particularly the one prize that has eluded him throughout a career now well into its second decade in the game.
"There are still things I want to win at club level. The same goes for the national team," Kane said.
With Bayern and Kane both aware of how close they came against PSG, the striker was direct about what stands between the club and the trophy he craves most.
"The question is whether we can make the small difference needed to go through and win the Champions League. That's my goal. It's the whole team's goal."
Bayern begin their Champions League campaign against Bodø/Glimt at the Allianz Arena, the opening fixture of a reshaped league-phase format that will test Vincent Kompany's squad depth from the outset.
Kane, who has been the subject of transfer speculation linking him with a return to the Premier League and Manchester United, remains focused on delivering silverware in Munich before any decision about his long-term future is made.
The striker's frustration with last season's exit was evident at the time, with Kane admitting afterwards that Bayern's finishing had been wasteful across the tie and pointing to a missed second-yellow card for PSG defender Nuno Mendes as a moment that might have changed the outcome.
That semi-final defeat followed a run that had included eliminating Real Madrid in the quarter-finals, a result many had considered a springboard toward Bayern's first Champions League triumph since 2020.
Kane has now spent three full seasons in Bavaria without adding the one trophy that continues to define outside perceptions of his career, despite prolific scoring records domestically and in Europe throughout that spell.
