Jurgen Klopp has said "it is not 100 percent sure" that Andy Robertson will be available to face Napoli in Liverpool's first UEFA Champions League game of the season on Tuesday at the Stadio San Paolo.
Per James Carroll of LiverpoolFC.com, the Scotsman did not train on Monday due to a knock, and he "will be further assessed by the club’s medical team in Italy" before the Group E clash.
Klopp said: "Robbo didn't train today and we have to see. It is not a major thing, it was more precautionary today, but it is not 100 percent sure [he will be available].
