Jürgen Klopp has offered an update on the injury that ruled Roberto Firmino out of Liverpool's visit to Manchester City on Thursday.
The No.9 was forced to miss the Carabao Cup fourth-round tie at Etihad Stadium due to an issue sustained in training earlier this week.
Speaking before the fixture, Klopp told Sky Sports: "We play mainly with the players who could do all the sessions now and had a break – apart from Bobby, who unfortunately got injured two days ago in training.
"Not a big one but big enough for this period. That's why Darwin is now starting. He could've started anyway but Darwin is starting now.
"Apart from that, all the others could've played. I'm pretty sure Hendo could've played, Fabinho could've played, Ali could've played but that's clear with the competition.
"Just Virgil only arrived yesterday. We gave him two days more because he's really our all-time player. He played all the games for us, played all the games for Holland, so we thought it makes sense to give him two more days because obviously a really important part of the season is ahead of us and we are really desperate to make sure we do it the right way."
