Napoli should reportedly have Dries Mertens back in the squad to face Granada and the Belgian could get some minutes towards the end.
With the absence of Victor Osimhen, who spent the night in hospital after the 4-2 defeat to Atalanta last weekend, eight players will be missing when Granada arrive in Naples this week.
But Tuttosport reports Mertens resumed training yesterday, after a month out.
He should be called up for the match against the La Liga side and could play the last 15 minutes, according to the newspaper.
Napoli need to turn around a 2-0 defeat from the first leg at the Estadio Nuevo Los Carmenes last week.
