Mane has recovered from illness to join a 21-man travelling squad for the Group C encounter at Parc des Princes on Wednesday night.
Kamil Grabara and Divock Origi have not shaken off similar complaints, however, and will miss the trip.
“I got a message yesterday that Divock, Sadio and Kamil were ill,” Jürgen Klopp told Liverpoolfc.com.
“They came in and we checked them again – Sadio trained today as normal and is available.”
Gomez was not risked for Saturday’s 3-0 victory at Watford after sustaining a knock in training ahead of that game but is at Klopp’s disposal once again.
“That’s all good,” said the manager. “All the rest is like it was before.”
