The Brazil international joined from Roma in the summer in a deal worth up to £66.8m.
Alisson "From the first second he felt really familiar and that's the truth."
"A good player, and good goalkeeper but a good player. For a goalkeeper that is cool. He gives us more opportunities. I like that.
"We have this Brazilian group plus Spanish with Alberto [Moreno] so that helps them even though Alisson and Fabinho's English is quite good. I'm very happy so far and hopefully it stays like this."
