Liverpool have confirmed that key trio Mohamed Salah, Roberto Firmino and Alisson Becker will all start against Lyon.
The Reds' summer results have been uninspiring with defeats to Borussia Dortmund (3-2) and Sevilla (2-1), but a 3-0 thrashing from Napoli at Murrayfield on Sunday will have set alarm bells ringing.
With the start of the 2019-20 season less than two weeks away, Jurgen Klopp and his defence have work to do - and the Anfield coach will be relieved at the return of No.1 goalkeeper Alisson.
The Brazilian shot-stopper returned to training this week along with Firmino after the pair were granted extended breaks after a triumphant Copa America with the Selecao, and will be working with team-mates at the club's training camp in Evian, France.
Salah is also back following the Africa Cup of Nations, though Sadio Mane is still on holiday after Senegal's run to the final.
There is further good news with Naby Keita and Xherdan Shaqiri recovering from adductor and calf injuries respectively, and both start for the Reds.
Curtis Jones and Nat Phillips have not made the trip to France, instead being sent back to U23s training with loan moves more likely than first-team football at this point, while Ben Woodburn has joined Oxford United on loan.
Summer signings Harvey Elliott and Sepp van den Berg have made the cut along with young forward Bobby Duncan, but Ryan Kent remains on Merseyside due to illness.
