Rennes have announced the sale of Yann M'Vila to Rubin Kazan, but the deal remains shrouded in mystery with the Russian club currently under a transfer embargo.
Reports earlier in the week suggested Rubin had gazumped Queens Park Rangers in the race for M'Vila by lodging a bid of €11.5 million, exceeding by some €1.5 million the fee Rennes had hoped to receive.
However, last month the Russian FA banned Rubin from registering any players in January as punishment for unpaid wages owed to former striker Roman Adamov, who was at the club from 2008 to 2012. Rubin were also fined $3,250 and ordered to pay all outstanding money to Adamov within 30 days.
But Rennes issued a statement on Wednesday evening which read: "Stade Rennais, FC Rubin Kazan and Yann M'Vila have reached an agreement for the permanent transfer of the French international. After the traditional medical visit, the Rennes midfielder joined the Russian club officially on Wednesday evening."
However, Rennes made no reference to Rubin's transfer embargo with the club hoping to meet with representatives from the Russian FA to get the deal for M'Vila sanctioned.
There is nothing to stop Rubin signing the player, but they would not be able to register him with the Russia FA under the terms of the embargo - and therefore he would not be able to play for the club until next season.
