Napoli coach Francesco Calzona was left angry with the players after defeat at Empoli.

Alberto Cerri struck for Empoli's 1-0 win.

“The approach to the game was ferocious from Empoli, whereas we were sluggish from the start. We were timid and this is inconceivable, but the responsibility has to be mine, because evidently I was not able to express to them my desire to go as far as possible," Calzona told DAZN.

“Clearly, if we don't win games and even lose them, it is difficult to think about reaching this target. We must try in every way to honour the jersey, to give more and above all to start stronger.

“There is some disconcerting data, we are the team that scored the fewest goals in the opening 15 minutes. We didn't have the right attitude, Empoli did, and they deservedly won the game.

“It was a wasted opportunity. It's true we are too sluggish and lazy, both on and off the ball. This lack of determination to win the ball back is something we've had since I arrived. It must be my fault, as I was unable to express the importance of pressing high.

“If we dominated possession in the second half and didn't get a shot on goal, that means we are predictable, which again is unthinkable considering the quality in this team. I have to take responsibility."
