Italian media outlet Gazzetta dello Sport, as quoted by talkSPORT, is reporting that the Belgium international has been offered a new contract that would improve his terms and secure his stay in Naples until 2022.
The same article states that the 31-year-old is attracting interest from Chelsea FC following speculation suggesting former Napoli boss Maurizio Sarri will replace Antonio Conte at Stamford Bridge.
According to the same story, outspoken Napoli president Aurelio De Laurentiis is desperate to keep the Belgian forward at the Serie A club beyond the World Cup.
Mertens scored an incredible 18 goals and made six assists in 38 games in Serie A last season to help Napoli challenge Juventus for the Italian top flight crown.
Chelsea FC are facing speculation surrounding the future of their current manager Antonio Conte after the Blues finished in fifth spot in the Premier League table.
The Blues were 1-0 winners against Manchester United in the FA Cup final at Wembley last month thanks to Eden Hazard’s winner from the penalty spot.
Mertens would have the chance to link up with fellow Belgian stars Hazard and Thibaut Courtois at Stamford Bridge.
