Napoli midfielder Marek Hamsik has admitted that he is concerned for the future of the club should both Edinson Cavani and coach Walter Mazzarri leave.

Cavani's goals have fired Napoli into next season's Champions League but he has been the subject of constant speculation surrounding his future.

"It's difficult to think of a Napoli without Cavani and Mazzarri; we would lose a player who has scored more than 100 goals and a coach who has turned us into challengers for the Scudetto," Hamsik told Reuters.

"I hope Mazzarri and Cavani don't go, so that we can make this Napoli great. In the last three years, we have obtained great results and we want to continue like that."

Napoli have sealed second place in Serie A.
