Alisson Becker is convinced Liverpool can call on a "fantastic player" once Arthur Melo gets up to speed at his new club.
The Reds signed Arthur on a season-long loan from Juventus on transfer deadline day last week in an attempt to address their availability issues in midfield.
The 26-year-old Brazil international could make his debut on Wednesday having been included as part of the squad that travelled to Italy for the Champions League group opener against Napoli.
