It's clear that both players are waiting for other numbers to be made available before they have their official numbers confirmed.
As the boss explained to Liverpoolfc.com, those not involved in Dublin will start against the Italian side, while it's also the chance to experience Anfield for the first time for some.
Alisson started training with the Reds earlier this week following a break after the World Cup and is now set to take his bow this weekend.
Ings joined Liverpool from Burnley for just £6.5 million, meaning the Reds are in line to make a big profit on the forward who has been plagued by injuries during his time at the club.
Liverpool will consider selling Sheyi Ojo before the transfer window closes, despite Jurgen Klopp's assertion the club only wanted to send him on loan.
"I think goalkeepers are important to any team".
"Each player in the world needs training and time to adapt to his teammates".
With under a week to go until the transfer deadline, Ings' price may fall as it becomes clear that no club will match the Merseyside club's demands, but whether it will come down to a number we can afford, it's questionable. He obviously has a real presence, he's smart, he's very nice and it's good to have him around.
