Jurgen Klopp has not ruled Naby Keita out of Liverpool's top-of-the-the-table clash with Manchester City, even though the midfielder was taken to hospital after Wednesday's Champions League loss to Napoli.
Keita was withdrawn just 19 minutes into the Reds' 1-0 defeat in Italy due to a back spasm and went to a Naples hospital for precautionary checks.
However, the 23-year-old's problem is not considered major and there is a possibility he is available for the Reds' Premier League clash with fellow high-fliers City at Anfield on Sunday.
Asked for an update on Keita at his Friday news conference, Klopp said: "Not 100 per cent sure, he had a back spasm. So we have to wait a little bit.
"He will be in today; if he can do something on the training ground, I don't know. I spoke to the doc this morning but he didn't know. We have to see him again in a few minutes and then we will make a decision about that.
“We don't know in this moment as well if he can train tomorrow, we have to see. It didn't look too serious, so there's a chance but we don't know."

Keita has featured in seven Premier League matches since joining Liverpool over the summer with four of those seven appearances being starts.
The midfielder also went a full 90 minutes on Liverpool's League Cup defeat to Chelsea.
If Keita does miss out on this weekend's clash, he could be replaced in midfield by Jordan Henderson, who enteres for the former RB Leipzig midfielder against Napoli, or Fabinho, who is still searching for his first Premier League start.
