Krasnodar to end Mamaev contract after Russian assault

On Monday the players, both former Russian internationals who have courted controversy in the past, attacked a Russian trade ministry official in a Moscow cafe after he complained about their behaviour.

Russia's interior ministry has opened a probe into the incident.

Krasnodar want to end Mamaev's contract as soon as possible while Kokorin's role in the incident was described as "disgusting" by Zenit.

"We are currently looking into how to terminate a contract with the player," FC Krasnodar said in a statement.

"Unfortunately, contracts are drawn up in such a way that they protect professional athletes to the greatest possible extent. But we will do everything to get it done."

The club said Mamaev, 30, would have to pay "the largest possible fine" and would be barred from training with the first team for the time being.

Video footage which surfaced on the internet showed Kokorin, Mamaev and their friends throwing chairs at trade ministry official Denis Pak, who had to seek medical assistance before reporting the incident to the police.

"What we saw in the video is outrageous," Krasnodar added.

FC Zenit said Tuesday Kokorin, 27, would be disciplined pending the outcome of the police investigation.

"But currently, Zenit management and fans are feeling nothing but disappointment that one of the country's most talented footballers behaved in a disgusting manner," the club said in a statement.

It is not the first time the players' behaviour has raised eyebrows.

Russia's Football Union suspended the pair in July 2016 after a video emerged from a Monte Carlo nightclub where Mamaev and Kokorin allegedly spent $296,000 (258,000 euros) on a champagne-fuelled party following Euro 2016, where Russia flopped.

Kokorin later apologised for his behaviour and was welcomed back into the national team.

He has scored 12 goals in 48 matches for his country, but sat out this year's World Cup with a knee injury.

Mamaev last played for the national side at Euro 2016, when they finished bottom of their group.
