Cesare Prandelli has resigned from Fiorentina and accepts his coaching career could be over after revealing he has been "going through a period of profound distress".

Prandelli joined La Viola in November for a second time after previously managing the club between 2005 and 2010 before taking over from Marcello Lippi as Italy's national team boss. 

He replaced Giuseppe Iachini in November, but oversaw just five wins in 21 Serie A games to leave Fiorentina 14th in the table. His last game in charge was Sunday's 3-2 home defeat to Milan.

In a statement posted on the club's official website, Prandelli said he stood down after a "dark cloud" had developed inside him.

"This is the second time I've left Fiorentina," he said. "The first time was not my decision, but this time it is. In life, as well as the good times, there are also dark moments which can get on top of you.

"I have been going through a period of profound distress which is preventing me from being who I really am. I began this experience with joy and love, spurred on by the enthusiasm of the new owners. 

"It's likely that my love for the city, and the memories of the great moments I've experienced here, made me blind to the early signs that something wasn't right inside.

"My decision has been guided by the enormous responsibility I have towards the players, the club and – last but certainly not least – to the Fiorentina fans, for whom I have great respect.

"All players at this level have talent, and when you have talent you are perceptive – I wouldn't want my distress to be picked up and affect the team's performances. 

"Over the past few months, a dark cloud has developed inside of me, changing the way I see things. I came here to give 100 per cent, but I now feel that this is no longer possible and therefore I have decided to step back for the good of everyone involved.

"I'm aware that this could be the end of my career as a coach, but I have no regrets and don't wish to have any. 

"The world I've been a part of for my whole life probably isn't right for me anymore – I no longer see myself in it. 

"I've certainly changed, but the world is moving faster than I thought, too. That's why I believe the time has come for me to stop being swept along, stop for a while and rediscover my true self once again."

Inter assistant coach Cristian Stellini has challenged Nicolo Barella to take the next step in his career by adding more goals to his game after scoring in Friday's 2-0 win at Fiorentina.

The Italy international curled in a delightful opener after 31 minutes at Stadio Artemio Franchi and Ivan Perisic added a second as Inter moved top of Serie A.

Barella, who was earlier denied by a fine Bartlomiej Dragowski save, now has three goals and five assists in 21 league outings this term.

That makes 2020-21 the midfielder's best Serie A season in terms of goal involvements, though he did net six times for Cagliari in the 2017-18 season.

Stellini, who was filling in for suspended head coach Antonio Conte against Fiorentina, hopes to see Barella build on those figures in the remainder of the season.

"He is still growing, like Lautaro [Martinez] and many other young players in the squad," he told Sky Sport Italia. "The next step is a few more goals."

Barella's two other goals this season came from inside the penalty area, the 23-year-old having converted just one of his four Opta-defined big chances.

"I was missing them before, but now the goals are starting to come," Barella said. "Today I could have done better, but I am putting myself in good positions."

Perisic also impressed in the routine victory in Florence before leaving the pitch with a knock 10 minutes from time.

The 32-year-old, linked with an exit in January, was on target for just the second time in 19 league outings this term and Stellini was impressed with the winger's display.

"He adapts well and sacrifices a lot," Stellini said. "Before he was a protagonist in the opposition's half, while today he also helped at the other end.

"He is a precious player for us because he is very physical and can cover the whole wing very well. We are convinced and satisfied with what he is doing."

Victory for Inter was their first away at Fiorentina in the league in seven attempts since 2014 and marked the first time they have won successive Serie A matches in 2021.

The Nerazzurri, beaten 2-1 by Juventus in the first leg of their Coppa Italia semi-final earlier this week, are now a point above Milan ahead of their bitter rivals' game in hand against bottom side Crotone on Sunday.

Romelu Lukaku wasted a couple of opportunities and had a goal ruled out, while Dragowski produced four saves in total, but Stellini had no complaints with his side's profligacy.

"We are satisfied with the chances created," he said. "Our forwards have worked well in partnerships, creating several opportunities to score.

"Our players are very generous and sometimes can lose control, but today they were tidy and precise. It wasn't easy so I congratulate the team.

"We don't think about other sides, only our own path. After the game three days ago, it was not easy to come here on a difficult surface."

Fiorentina had won their previous two home league matches and were unfortunate not to be on level terms at half-time as Giacomo Bonaventura struck the crossbar.

However, head coach Cesare Prandelli accepted that his side were second best and did not deserve anything from the game.

"We reacted well to Inter's goal but then opened ourselves up too much," he said. "They were superior to us, but I don't blame my players for anything.

"When you face a team with players that Inter have, who punish you with speed, it can be hard. It's sometimes easier to just give credit to your opponent."
