Corcorin said after arriving in Florence for a medical examination: “I am here to score many goals. I am happy to be in Italy and I chose Florence because it is the most beautiful city in Europe, and the club is good and has a great history.”
Cocorin, 29, will wear the 91st shirt, and the duration or value of the deal has not been announced.
The Russian international has played 48 matches for his country, scoring 12 goals.
During his club career, he wore the jerseys of Dinamo Moscow, Inge Machkhala, Zenit St. Petersburg and Sochi.
At the beginning of this season, he joined the Russian ranks of Spartak Moscow and scored two goals in 10 matches.
Fiorentina ranks 12th with 21 points after the end of the first round of the Italian league.
The Russian was imprisoned in May 2019 after he was found guilty of sabotaging property, assaulting an official from the Ministry of Trade with a chair and beating a driver in October 2018, in the company of Pavel Mamayev, the Krasnodar midfielder.
The couple was walking on a drunk street before attacking two people, including a Ministry of Commerce official and a driver for a TV presenter.
“I hope this will teach them a lesson for them and for all the athletes,” the Russian Sports Minister said after the two internationals were jailed.
Kokorin was sentenced to 18 months imprisonment in Moscow, while Mamayev was sentenced to 17 months in prison, and the first was discharged in September of the same year.
Kokorin missed the 2018 World Cup in Russia with his country’s national team, due to his injury to the cruciate ligament during a European League match between Zenit and Red Bull Leipzig.
This is not the first incident of the duo, as he was involved in what newspapers described at the time as a “scandal” after a party full of alcohol was held in Monaco after Russias early bidding farewell to Euro 2016, and he was excluded from the first team to participate with the reserve team.
Kokorin returned to wear the Russian Zenit shirt, then joined Sochi on loan, and then on loan to Spartak Moscow.
