Jurgen Klopp says he is awaiting further assessment to determine the seriousness of Naby Keita's latest injury.
The Liverpool midfielder hasn't played a minute this season after missing the opener at Fulham with illness before failing to get off the bench in the 1-1 draw with Crystal Palace last week.
The Guinea international was absent from the 2-1 defeat to Manchester United on Monday evening after suffering a setback on Sunday. Klopp is unsure about the severity of the problem for the £52m midfielder as he lamented his growing injury concerns that sees him without as many as nine first-team players.

"Naby was injured yesterday," Klopp said. "We need further assessment but it doesn't look like he's back in training tomorrow, but we need further assessment. It's just [it happened on] Sunday and then maybe we will know more tomorrow, I don't know.
"We had 15 senior outfield players in training, I think. That’s obviously not cool, but I liked the line-up for the game tonight. And we had some good performances, obviously not enough to win the game.
“But I think we all know that if we score the equaliser it would not be the biggest surprise in the world. It would have been a deserved draw after a start where United looked sharper than us, but not for too long.
“Our situation is how it is, not perfect but good enough to play better tonight and good enough to have won the game tonight had we played slightly better."
With Keita sidelined, Klopp is also unable to call upon Curtis Jones, Ibrahima Konate, Joel Matip, Alex Oxlade-Chamberlain, Diogo Jota, Caoimhin Kelleher, Thiago Alcantara and new signing Calvin Ramsay, while Darwin Nunez still has two games of his suspension to serve.
