Napoli captain Lorenzo Insigne is a doubt for their upcoming Champions League clash with Liverpool, having sustained a muscle problem in the 4-3 defeat to Juventus.
Carlo Ancelotti's side host Liverpool on Tuesday in the first game of the group stage, hoping for a repeat of last season's result, when they beat the Reds 1-0 courtesy of a last-minute winner from Insigne himself.
However, the forward missed Italy's Euro 2020 qualifiers against Armenia and Finland over the international break and, as reported by Football Italia, there are concerns over whether he will be available for the Liverpool game, having trained alone on Wednesday.
