DUBLIN -- Jurgen Klopp said he was "really pleased" with Alisson Becker's Liverpool debut, calling it an "all-round good performance" in the 5-0 thrashing of Napoli on Saturday.
Alisson played the full 90 minutes of Liverpool's penultimate friendly of the preseason, recording a clean sheet and impressing the Aviva Stadium with a good range of distribution throughout.
The Brazil international, who joined from Roma for £65 million last month, had a relatively quiet evening as James Milner, Georginio Wijnaldum, Mohamed Salah, Daniel Sturridge and Alberto Moreno all got on the scoresheet in Dublin.
"He's quite a good footballer -- probably as good as the goalie he is!" Klopp told a news conference. "An all-round good performance for the first game, especially because I think everyone can imagine what happens inside a human being in a situation like that, playing the first game after all the things that were written about it and all that stuff.
"Playing against Napoli, it was the strongest side we played so far, 100 percent -- they had nearly a full squad here and it can look completely different.
"He was very, very aware of all situations when he was needed behind a high last line. We involved him a lot in our build up, but we need to get used to that a little bit more still -- that's clear [and] he needs to get used to it a little bit more, but there were a lot of good build-up situations, so that helps.
"But at the end he's there to catch balls and he did that in all the decisive moments today, so I'm really pleased."
Meanwhile, Klopp revealed Milner had to receive 15 stitches after a clash of heads during the second half of the Napoli game. The midfielder was forced off in the 55th minute following a nasty aerial collision with Mario Rui.
Klopp believes the injury to the 32-year-old was the one negative of a day where his team delivered an extremely encouraging display.
Speaking to the club's official website, the Liverpool manager said: "I knew that he would get stitches because we saw it on the pitch.
"He's in the dressing room so I have to see him first before I can say more. That's obviously the big shadow over that game."
Klopp added: "To be honest, the result is something I'm really not interested in, [more] big parts of the performance.
"Preseason, you can lose a game like this and it [doesn't mean] everything you did before was wrong and if you win 5-0 it [doesn't mean] everything was right. That's pretty much the case.
"It was, in a lot of moments -- especially around the goals and a few more moments -- brilliant."
