according to a couple of sites i have read (among which passioneinter), politano and de vrij should be called up for this match but not be in the starting lineup, especially politano while there are more chances for de vrij to start.
i haven't seen anyone mention keita among the injured players, so he might have recovered from whatever injury he had (there was this rumour he had a relapse as a consequence of a prank pulled on him but the tv show "le iene", but i don't think we'll ever know for sure).
no one in our team is suspended but SIX players are one yellow away from suspension: Borja Valero, Gagliardini, Lautaro Martinez, Perisic, Politano, Skriniar.
as for napoli, insigne's presence is in doubt.
