Reds boss Jurgen Klopp is still without long-term absentees such as Joel Matip, Adam Lallana and Emre Can for Tuesday night's game, but right-back Nathaniel Clyne has been back in training after recovering from the muscle issue that sidelined him for Saturday's 2-2 draw at West Brom.
The Reds rested some key men for the game at the Hawthorns and will go into the clash against the Italians relatively fresh.
Klopp's sides have developed a habit of blowing teams away in concentrated spells, highlighted by their three goals in 19 first-half minutes to take the Champions League quarter-final tie away from Manchester City.
He likened it to the manner in which the great Manchester United side of the 1990s and 2000s operated.
Klopp said: "Is there something with Alex Ferguson, Man United. At a specific time they scored always twice?
"Score, score? That is the opportunity. Score once, do it again. Use the momentum in the game. Of course we talk about it, of course we want to use that, but you still have to score.
"The team is a really enthusiastic team. In a good moment, they jump and that's really good to see.
"On the other hand, that's why the two Man City games were really special. We dealt with the very difficult circumstances in the two halves here and there on a high level.
"That brought us to the semis, not that we can score one, two, three in a row. In the moments when we are not in charge of the game, we are still in the game, that's a very important thing and that helped us massively."
