Zenit St. Petersburg have sent captain Igor Denisov (pictured) and forward Alexander Kerzhakov to the club's youth team after "internal problems" (Reuters via FourFourTwo.com).
At the club's official website, FC-Zenit.ru, the club announced 29-year-old Kerzhakov had joined the youth team for "improper behavior."
In a separate announcement, the club said Denisov had been sent to the youth team "indefinitely."
This measure is related to the fact that Denisov made an ultimatum to the club and refused to take the pitch against Krylya Sovetov, demanding that his personal contract be reviewed.
Denisov first made his contractual demands, which the club considers to be unfounded, in May, 2012. Denisov`s contract is valid until 2015, and his salary is one of the highest not only in FC Zenit, but in the whole Russian Premier League.
The Reuters article speculates that "several senior Zenit players" are unhappy over the club's big-money signings of Brazilian attacker Hulk and Belgian midfielder Axel Witsel.
