Klopp is delighted with what he's seen from his players this season.
“I think that the players knew after five days what my ideas were," Klopp said.
"It was clear that the players knew me and knew Dortmund. This is why it was clear how we wanted to play, but we didn't want to push everything that way right from the start, we wanted to utilise the qualities of the players and give them more confidence so they would have that belief that they are the right players for Liverpool.
“But of course you need time until you can see that on the pitch. I don't know how much time it took, but it certainly took some time. In the first year we reached the Europa League final and the League Cup final, we lost them both, but it was a very strenuous season.
“We qualified for the Champions League for the second season, in our third year we reached the final of the Champions League, and in the fourth season here we are again in the Champions League final."
