Napoli coach Luciano Spalletti admits defeat to Fiorentina is a title blow.

Napoli lost 3-2 at home to the Viola on Sunday.

"This is a very costly defeat and in certain ways was undeserved. Fiorentina played their game and earned the win, but we started strong, then tried to play too long and allowed them to take control of midfield," Spalletti told DAZN.

“When we conceded the second goal, it all became far more difficult. We have to take some of the blame for what happened, but it's so disappointing because the fans, the attitude of the whole team throughout the week was the right one.

“Fiorentina play man against man, Milenkovic pushes far up to chase his man and leaves these spaces we could've made more of. If you don't have the quality to dribble your way out of trouble, then you end up with long balls.

“Osimhen wasn't in the best shape today, as he skipped a couple of training sessions. He did well, but could've done better in these physical duels with Igor."

He added: “Of course things change, because clearly now it's all more difficult. We have no choice other than to be professional, try to win the next game and see what happens. It is no longer in our hands."
