Sadio Mane is a surprising, yet welcome inclusion in Liverpool's starting line-up against West Ham on Saturday evening.
The 25-year-old, who joined team training on Thursday after nursing a hamstring injury sustained while on Senegal duty, has missed the last five games in all competitions.
In his pre-match press briefing, Jurgen Klopp indicated the winger could feature for 20-25 minutes at London Stadium, but he has since proved he can feature from the off.
Alex Oxlade-Chamberlain, meanwhile, follows his first European start for the Reds by also getting his full top-flight bow. He will operate with Emre Can and Gini Wijnaldum - the latter shaking off an ankle issue - in the centre of the park, while captain Jordan Henderson misses out with a thigh injury.
Simon Mignolet returns in goal and will wear the armband with vice-skipper James Milner dropping to the bench.
As has largely been the case this season, Klopp rotates again at right-back with Joe Gomez coming in for Trent Alexander-Arnold.
Dejan Lovren is named on the bench after missing the previous two matches with a thigh injury, while Philippe Coutinho is still sidelined with an adductor problem.
Liverpool starting XI: Mignolet, Gomez, Matip, Klavan, Moreno, Can, Oxlade-Chamberlain, Wijnaldum, Mane, Salah, Firmino
Liverpool subs: Karius, Lovren, Alexander-Arnold, Milner, Grujic, Solanke, Sturridge
