Napoli’s joy at qualifying for next season’s Champions League has been clouded by uncertainty over whether they can keep the team together for next season.The futures of coach Walter Mazzarri, who has transformed the team since replacing Roberto Donadoni in October 2009, and Serie A leading scorer Edinson Cavani will both be in the balance once the season ends."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,” said forward Marek Hamsik.Mazzarri, whose side host Siena on Sunday, declined to contemplate the future. "I want to get as many points as possible and then I will talk to myself and decide what to do,” he said.He led Napoli to sixth place in his first season in charge, followed by a third place the next season which earned them their Champions League debut.Uruguay forward Cavani joined the squad at the start of the 2010/11 season and has scored 102 goals in 136 appearances in all competitions since then.He has a 63-million-euro ($82.79-million) buyout clause in his contract and there is speculation that Manchester City and Real Madrid are among the clubs prepared to cough up.Only the top two teams in Serie A qualify for the Champions League group stage with the third-placed side having to go into the final qualifying round.AC Milan will clinch third spot if they beat AS Roma at home on Sunday or if Fiorentina, four points behind in fourth, lose at home to relegation-threatened Palermo.
