Speaking before the stalemate at Old Trafford, Jurgen Klopp revealed there was “no chance” Salah could feature, and had cast doubt over his availability for Wednesday night.
Salah scored twice in the 4-3 victory over Salzburg last time out in the Champions League, including the 69th-minute winner, and his involvement against the Belgian champions is a boost.
Adam Lallana may be handed an opportunity after his late equaliser against United, with the 31-year-old also part of the light session led by Conall Murtagh.
Youngsters Neco Williams, Harvey Elliott and Rhian Brewster joined the first team, but with the under-19s playing Genk in the UEFA Youth League earlier on Wednesday it is more likely they are part of Barry Lewtas‘ group.
Xherdan Shaqiri is still sidelined, with the winger returning to Switzerland to undergo treatment, attending the Roger Federer match in Basel on Monday.

Defenders: Van Dijk, Lovren, Gomez, Robertson, N.Williams
Midfielders: Fabinho, Wijnaldum, Henderson, Keita, Milner, Oxlade-Chamberlain, Lallana
