Napoli coach Rudi Garcia is counting on Victor Osimhen this season.
The star striker has been linked with a big money move away.
But Garcia said: "He's under contract, he arrives tomorrow with everyone else.
"I repeat, When I met (president Aurelio) De Laurentiis we agreed on ambition. The president is very ambitious, he did great things last year and doesn't want to stop.
"We will have a quality team."
