A 3-0 defeat to Napoli followed the Viola's Coppa Italia defeat to Juventus and the coach has admitted he has some concerns

Vincenzo Montella has admitted he is "worried" about Fiorentina 's form after an "ugly" defeat to Napoli on Sunday.

Rafael Benitez's men ran out 3-0 winners thanks to goals from Dries Mertens, Marek Hamsik and Jose Callejon, adding further misery to the Viola's week after they were eliminated from the Coppa Italia at the hands of Juventus on Tuesday.

Montella's men have won only three of their last eight in all competitions and the coach has has some concerns over the state of his team's mental strength.

"It was ugly. We had no character, no heart - that is worrying," he told reporters. 

"We didn't have any incisiveness or pace to us and we could have conceded more. We had no security in defence and no conviction.

“We wanted to control the game early on, but we didn’t have the right approach. I have not seen a team as superior as Napoli were.

"For the first time I must say that I expected much more from my team. I could not recognise them out there.

“Physically, we are fine, so maybe it is psychological, because the defeat to Juventus has affected us badly."

Gonzalo Higuain looked to have given Napoli a fourth goal as a shot struck the bar and bounced over the line, but the goal was not given and Montella downplayed the incident.

"Nobody saw it clearly because the shot was so fast," he said.

"These things happen and fortunately it didn't decide the result."

Aurelio De Laurentiis and Napoli continued their media blackout despite their victory, with all players and Rafael Benitez refusing to speak to reporters.
