Ex-Arsenal player Alex Song is owed £7.9m by Russian club Rubin Kazan who will host World Cup quarter-final

• Alex Song is owed £7.9million by Rubin Kazan, who failed to pay his wages
• Russian club will play host to a couple of World Cup knockout round matches
• Song is currently a free agent after leaving Rubin ten months ago due to dispute
• FIFA are exploring possible sanctions including expulsion from European games 

Former Arsenal and Barcelona midfielder Alex Song is still owed a whopping £7.9million by Russian side Rubin Kazan.

Song was one of many players who had their contract terminated due to Rubin's inability to pay their player's wages.

The Kazan stadium is hosting one of the World Cup quarter-finals as well as a round of 16 clash and several group games.

Song has been without a club for the last ten months and refused a £2.2m settlement with Rubin as they owe him more than twice that, according to The Telegraph. 

The 30-year-old is currently a free agent despite receiving offers from multiple clubs, as he is concerned that he will not get what he is owed by Rubin.

For now, Song is training in his homeland of Cameroon as he bids to maintain his fitness. 

Meanwhile FIFA are threatening Rubin with sanctions of both a financial and football nature. The club could even face expulsion from future European competitions.

The side were plunged into financial crisis last year, with Song one of a few players still waiting to be paid.

Rubin are owned by Tatar-American Investments and Finance company, whose president Radik Shaimiev is named as the 88th richest man in Russia.

The club made a name for themselves in the Champions League by reaching the group stages on three separate occasions, including one year in which they beat Barcelona.

They also reached the knockout stages of the Europa League and had previously made a number of high-profile signings, including Song, before financial troubles hit the club.
