Napoli are optimistic they could have Lorenzo Insigne back for the game against Roma and fit to start with Arsenal.
The captain was ruled out for three weeks with a muscular injury during the warm-up of their Europa League trip to RB Salzburg last Thursday.
According to Sky Sport Italia, Insigne is responding well to treatment and could be ready for the Serie A showdown with Roma on March 31.
There are another two games after that, with Empoli and Genoa, before the first leg of the Europa League quarter-final at Arsenal on April 11.
This would allow Insigne to get some time on the field to regain match fitness.
