Klopp said: “I didn't think it would happen that quick.
“It was a nice story and now the next one is a nice story. It's a massive difference, obviously.
“I don't think a few years ago anyone would have spent that for a keeper. It was always like a striker yes, if you need a winger yes, but please if you need a keeper bring your own one through from the youth or something.
“I don't know now if it will be like that with all goalkeepers in the world but I said the world changed. The money was there and someone asked for it. Bilbao was never a good partner for negotiations: 'You pay it or leave it, we don't care.'"
Will the Kepa deal ease the scrutiny on Alisson?
"Pressure is everywhere and stuff like that but you only have to deal with it. You know it, but don't feel it, so go on," Klopp said.
"If Alisson makes a mistake - hopefully not but if he makes a mistake – if you write for that money he's not allowed to make mistakes, they still happen.
"Internally, we will deal with that. What happens from outside, you can not control. Newspapers interested in us might say: 'No problem, he's a human being.'
"Other clubs and other managers might go for it, if it helps, but that's not interesting for us."
