Liverpool fullback Andy Roberston is a doubt for their UEFA Champions League clash against Napoli.
The Reds are set to face a tough test against the Italians, who they have played in the competition in recent years.
And they could be without their key left back Roberston, who suffered a knock in their most recent Premier League clash against Newcastle.
"Robbo didn't train today and we have to see," Liverpool manager Jurgen Klopp told the club's website.
"It is not a major thing, it was more precautionary today, but it is not 100 per cent sure [he will be available].
"We will have to test it tomorrow and then we will see."
