In his first press conference back in October the German made the pledge after insisting he saw qualities in the squad he inherited from Brendan Rodgers where others saw none and would ensure people - players, the public, critics - changed their opinion.
And on the eve of the club's first European final for nine years, Klopp believes he has delivered.
"I came here because I was really convinced about the qualities of these players and this squad, despite the doubts people had," he said.
"To see how they have reached this final gives me a really good feeling.
"When I came here there was a big amount of doubt about these players and now I am really happy they can show how strong they are and it is a big opportunity to make the final step this season and achieve something.
"I don't feel the pressure. I cannot change. I feel opportunity, I feel the pressure of the game and developing players.
"I don't think I've ever felt doubt around me. If that's right I don't know but it makes me completely free to make decisions and for my team and myself to be free to develop together.
"I am really pleased for the boys and that they can be part of the moment with this team.
"We have a big chance and winning tomorrow will make it much more easy for you to see it as a success - and I try to help."
Liverpool are favourites to win in Basle despite Sevilla looking to become the first team to win the competition for three successive seasons.
This current Reds side lack similar European experience with even Klopp's record in finals nothing to write home about.
The German has lost his last four but intends for that to change in Switzerland.
"I don't think to be honest I deserve some luck," he added.
"There are only two possible things in a final, you win or lose. The only thing is the performance.
"You would have seen that all the teams I was involved with have done really well.
"I am not frustrated by my final record, it could be a little bit better, I was for sure not happy after finals when I didn't win, but when it's over, it's over.
"And I know we performed to the right level and they were very close games.
"At home I have a little too many silver medals, that's true, but it's better than having no medals.
"For me, when you try hard, and keep trying, then you get there eventually."
