Luciano Spalletti says, Victor Osimhen would be "100 percent" available for Napoli's major Champions League match against Milan the following week.

The striker was not present for his team's quarterfinal first-leg defeat on Wednesday, as the Partenopei lost 1-0 at San Siro thanks to a first-half goal from Ismael Bennacer.

With 21 goals this season, Osimhen is the Serie A scoring leader and has played a key role in the club's commanding lead in the Scudetto battle.

But having sat out this week's game with a groin injury, Spalletti has given assurances he will feature for their home tie next week against the Rossoneri.

"Victor Osimhen will 100 per cent be available for the return leg at [Stadio Diego Armando] Maradona on Tuesday," he said. "He will be there."

Spalletti will also have to rethink his plans in light of Andre-Frank Zambo Anguissa's dismissal, with the midfielder sent off after a second yellow card for pushing Theo Hernandez.

The Cameroon international will be suspended, as will defender Kim Min-jae following a late booking, but the coach has the belief his side will adapt to their loss.

"Any absence is damaging at this stage of the season, but we also have players who can fill in, which is why we are where we are," he added to Sky Sport Italia.

"We trust the squad. We are sad not to have Anguissa, as it feels unjust not to have him, but there's nothing we can do. I don't comment on the referee, that is not my role."

Napoli will return to Serie A action this weekend against Verona before they face Milan. The Partenopei are already enjoying their deepest run in Europe's premier competition.
