Alisson was a surprise absentee as Liverpool announced their starting lineup to face PSV Eindhoven in the Champions League, with the Brazilian withdrawing late.
Giorgi Mamardashvili has replaced Liverpool’s No. 1 as one of only two changes to the side which lost 3-0 to Nottingham Forest on Saturday.
This Is Anfield understands this comes due to illness, with Alisson missing his ninth game of the season already.
Alisson’s late withdrawal vs. PSV Eindhoven

Alisson‘s absence came as a late concern for Arne Slot, who was otherwise set to make just one alteration to the side humbled by Forest at the weekend.
It comes after an eight-game layoff due to a hamstring injury, which at least means Mamardashvili is no longer unfamiliar with the players around him.
Hugo Ekitike takes over from Alexander Isak in the only other change from Saturday.
Liverpool’s other tactical tweak: A change at right-back?

Slot may, however, have opted for a tweak to his lineup without any further changes in personnel, with Curtis Jones expected to take the right-back role.
Dominik Szoboszlai filled in for the absent Conor Bradley four days ago but the suggestion is that Jones will instead deputise against PSV.
This comes with both Bradley (muscle) and Jeremie Frimpong (hamstring) out along with Alisson (illness), Giovanni Leoni (ACL), Stefan Bajcetic (hamstring), Florian Wirtz (muscle) and Jayden Danns (hamstring).
Those absences meant Slot could only name a nine-man bench despite UEFA rules permitting 12 substitutes.
Liverpool’s group of reserves at Anfield includes goalkeepers Freddie Woodman and Kornel Misciur as well as youngsters Trey Nyoni and Rio Ngumoha.
Joe Gomez is not considered fully fit after requiring a painkilling injection to manage a knee injury, while Isak is still working his way back following a groin issue.
