Liverpool boss Jurgen Klopp says he faces a late decision over whether to play Naby Keita and Joel Matip against Atalanta.
The Reds are struggling with injury in defence with Virgil van Dijk and Fabinho on the sidelines.
In Saturday’s 2-1 win over West Ham, Nathaniel Phillips made his debut and impressed alongside Joe Gomez.
And the 23-year-old could be pressed into action again if Matip is unable to prove his fitness in time.
In midfield, Keita has not played since the 7-2 defeat to Aston Villa at the start of October.
Keita and Matip both trained on Sunday but could be short of fitness to feature in Italy.
“A lot, [but] I’m not sure about a new one. We have to see,” Klopp said in his pre-match press conference when asked for an update on injuries.
“Yesterday was recovery for some and normal training for the others, so now we have to see how the boys feel today.
“It’s pretty early now and I have not all the information, but I hope nothing serious.”

He said: “He is good, how players actually should be when they join us. He is in the best age, 23, already experienced, played a lot of Premier League football, made his way up in Portugal. He’s a really good boy and a really good signing. That’s the situation.
“We never hold players back in the beginning, it’s just that players usually need time to adapt. But I knew before it would not take too long for him because of the way Wolves are playing. Yes, they play a different system, but the intensity for Wolves is and was always incredibly high.
“There might be only one player who has to defend slightly less – not really a lot less, but slightly – is [Raul] Jimenez. But the boys on the wings, they had to run like crazy, so it was clear physically he will be fine. Technically, we saw he is good. All the rest is then about finding your feet, pretty much, in a new environment.
“The boys always make it easy for new players and Diogo is a very good guy; he is really open, his English is brilliant. It means it was easy for him to step into the team, in the squad, in the dressing room. Now he played. Of course he was involved in games, like they all will be involved in games. It’s special.”
