The Brazilian made a host of saves to keep the German side at bay and avoid conceding in the first leg of Liverpool’s Champions League last-16 tie, which puts Klopp’s side in a strong position to advance to the quarter-finals.
However, the manager insists “nothing changed” when it comes to his belief in Alisson, who he admitted is “too smart” to not dwell on his mistakes.
“Of course. My confidence, nothing changed in that if we talk about Alisson,” he told reporters on Friday.
“But we are all human beings, and Ali as well. He showed that in the last two games.
“That’s how it is, it’s not a problem. And of course it’s work, but most of the work you have to do with yourself. He’s doing that, definitely.
“It’s not about telling him, ‘come on Ali, you’re a world-class goalie’. He knows that.
“But he doesn’t get up in the morning and looks in the mirror and thinks ‘what I see is a world-class goalie’.
“If you make a mistake in the previous games it’s nothing you like. Humans are all the same, and Ali’s too smart to ignore it completely.
“There are other personalities who maybe would not struggle, but in the end, we can rely and he can rely on his quality as well, on his attitude, on how focused he is in a game.
“So no, I was not one second in doubt. Ali for sure did not have the best time between the two games, that’s how it is.
“But the Leipzig game was a really good one to get back. And here we are now.”
“It’s very important that we defend as a unit on our highest possible level,” he continued.
“Everybody knows how important the defence, in general, is for being successful, and in our case it’s no different.
“The Leipzig was a really good sign that we can deal with misunderstandings, we can deal with mistakes from the game before.
“We played a really good game in the defensive part, against a really tricky side.
“You can struggle a lot against them and we will probably realise that when we play the next time. But for that night, we did really well as a unit and that helped.”
