Antonio Conte has a lot of work to do.
Conte became Napoli's fifth coach in just over a year when he was hired in June and on Sunday saw his new side fall to a 3-0 defeat at Hellas Verona in their first game back in Serie A.
Dailon Livramento and Daniel Mosquera (twice) scored on their league debuts to give Verona victory on the opening weekend of the Italian league season and there was more bad news for Napoli as they lost key player Khvicha Kvaratskhelia to injury.
Napoli have been on a losing streak since Luciano Spalletti left last summer after leading the club to its first title in more than 30 years. The southern side finished 10th last season and had expected much better under Conte, who led Juventus and Inter Milan to the title.
However, they drew 0-0 with Serie B side Modena in the Coppa Italia on Conte's debut, going through on penalties, before Sunday's second-half horror show.
Conte's side had the better of the opening stages in Verona, creating chances through Matteo Politano, André-Frank Anguissa and Stanislav Lobotka before the home side almost gave them the lead in first-half stoppage time.
Verona defender Martin Frese played a terrifyingly short back pass to goalkeeper Lorenzo Montipò and Kvaratskhelia raced towards it, but Jackson Tchatchoua flew in to make a heroic last-gasp tackle.
Kvaratskhelia had to withdraw immediately afterwards, apparently stating that he felt dizzy.
Frese made another poor backpass moments later which forced Montipò into an acrobatic clearance.
Verona came out a different team after the break and Grigoris Kastanos fired a shot wide of the far post with their first real chance of the game before the home side took the lead when Livramento managed to latch on to Darko Lazović's cross to curl the ball into the bottom right corner.
Anguissa hit the crossbar in the 61st minute but Verona doubled their lead by winning the ball in a midfield duel and Ondrej Duda threaded it through for substitute Mosquera to finish past Alex Meret in the 75th.
Mosquera had only been on the pitch for two minutes. The Colombian striker doubled his tally in stoppage time after being completely unmarked by the Napoli defence.
