Alisson is set to sit out at least seven more games for Liverpool, with manager Jurgen Klopp not expecting him back until after the next international break.
The Brazil international goalkeeper has been sidelined since picking up an unfortunate injury on the opening day of the 2019-20 campaign.
He broke down against Norwich at Anfield and has not been seen since.
Initial fears that a serious problem had been picked up were eased, but Alisson is no closer to making a return to action.
He has already missed three Premier League games and the UEFA Super Cup, with summer signing Adrian taking his place in the Reds side.
Klopp admits that he is likely to require cover between the sticks for several more weeks, with Liverpool eager to avoid rushing Alisson’s recovery.
With a cautious approach being favoured, the 26-year-old will remain out of contention until mid-October.
