Jurgen Klopp hopes the injury Alberto Moreno picked up during Liverpool's Champions League victory against Spartak Moscow is not serious.
The Reds made certain of top spot in Group E by thrashing their Russian opponents 7-0 at Anfield. Philippe Coutinho grabbed a hat-trick while Sadio Mane scored a brace and Roberto Firmino and Mo Salah were also on target.
It was the second time Liverpool had scored seven goals in the group as they also managed the feat against Maribor.
However, Moreno had to be substituted during the game and may miss this weekend's derby clash against Everton.
Klopp said afterwards: "I think it's really strange this year in the different groups - there are a lot of really strong teams. I don't think it's very often you can face Bayern Munich and Real Madrid in the last 16 if you win the group. And Juve!
"But we had a little shadow on the night when Alberto Moreno needed to get substituted. In the treatment room, he was a little bit more positive, so maybe we are lucky and it's not too serious. We will see."
Liverpool can be backed at 4/11 to beat Everton at Anfield on Sunday and at 1/1 to keep a clean sheet in the Merseyside derby. They are also available at 5/4 to win the Champions League outright this season.
