The Irish province have now lost four of the last six finals.
After suffering their third consecutive Champions Cup final defeat, Leo Cullen is backing his players.
The Leinster boss believes his players will keep working with an improvement mindset after seeing his side fall to the now six time champions, Toulouse, after extra-time.
Connacht will provide Leinster with their next test in the URC this weekend as Cullen's side prepare for another run through the play-offs after the regular season.
The Westerners meanwhile, look set to miss out on a place in the knockout phase of the competition.
Cullen says his players are great ambassadors for the game in the region:
