"He will have "A. Becker 13" on his shirt for the game at the Aviva Stadium but supporters should note that this is a provisional, unconfirmed squad number for the Brazil worldwide".
"I'm very pleased [to work with Alisson], but first of all it's very important he can start now because the season starts in one and a half weeks. We should not waste time", Klopp told Liverpool's website.
"I can't wait for the season to get going now".
Loris has also been linked with a move away from Liverpool, though no official talks have been held and as yet the German remains at Anfield.
One exciting newcomer, Xherdan Shaqiri, signed from Stoke City, does know the English game.
Divock Origi's involvement is doubtful as a move to Valencia edges closer, and £20-million-rated Crystal Palace target Danny Ings is also not expected to feature as he also nears an Anfield exit.
Ings and Liverpool agreed on a parting of the ways earlier this summer and that could come to a head sooner rather than later with the England striker not set to travel with the team for the friendly against Napoli in Dublin.
"Those who can't start against Napoli will start against Torino".
The Italian outfit will be without former Liverpool target Piotr Zielinksi.
Liverpool ended the speculation by finally signing Alisson after the World Cup, agreeing a deal with Roma which could eventually see the Serie A side collect £65million (A$103m).
It will be interesting to see how Klopp uses Camacho this season, with the Portuguese youth winger likely to be a constant feature in the Reds' under-23's side.
