Napoli have Arkadiusz Milik back against Liverpool, who are without Divock Origi and possibly Andy Robertson.
Milik had been missing for the past month with an abdominal injury, but the striker has been passed fit for the visit of Liverpool tomorrow.
However, Elseid Hysaj is out and Gianluca Gaetano has been reserved by the club’s Primavera side, who take on the Reds in the UEFA Youth League.
As for the Champions League holders, Robertson has travelled to Naples but will require a fitness test in the morning.
Origi was Liverpool’s hero in the knockout stages last season, en route to their sixth European Cup, but the forward faces at least a couple of weeks out with an ankle injury.
“Robbo didn’t train today and we have to see,” manager Jurgen Klopp told his club’s official 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. The update on Div is that it is not too serious.
“We expect him [to be out for] between one and two weeks, but it depends a little bit on when he can deal with the pain.
“It is nothing really; it’s a feeling, but it should be fine.”
