Napoli owner Aurelio De Laurentiis has hit out at Chelsea boss Maurizio Sarri for failing to win a trophy at the Serie A club.
The Blues appointed Sarri in the summer, replacing Antonio Conte at Stamford Bridge following a three-year spell in Naples.
The chain-smoking Italian has never won any silverware as a manager, though he repeatedly ran Juventus close during his time at Napoli.
Indeed, in 2017-18, the club were just four points behind the Bianconeri, while they finished five behind in 2016-17 and nine out in 2015-16.
Despite that De Laurentiis has issued a stinging criticism of the 59-year-old, who has thus far overseen two victories for the Blues at the start of the Premier League season, beating Huddersfield Town and Arsenal.
