Serdar Tasci became the latest victim of the hostilities between Turkey and Russia according to his agent Ahmet Bulut.
Bulut who also represents Arda Turan was quoted by Fanatik as saying: “The fans at a game in Russia burned a Turkish flag which Serdar was not pleased about and the situation started to become unbearable.
“He felt uncomfortable with the situation and wanted to leave Russia. Schalke 04 were interested but Bayern Munich made a late bid and clinched the deal.”
Tasci parted ways with Spartak joining Germany giants Bayern Munich over the winter transfer window.
Spartak were fined 100,000 roubles ($1,446.45) after their supporters burnt Turkish flags during a Russian league game against Krylia Sovetov Samara by the Russian Football Union (RFU).
The incident occurred at the Otkrytie Arena in Moscow on December 4 2015, 10 days after Turkish forces shot down a Russian war plane near the Turkish-Syrian border.
Tensions between Turkey and Russia have spilled over into football with controversial moves such as players bans.
Russia recently outlawed domestic clubs from signing Turkish players according to the Independent.
Tasci would have been unaffected due to being a German and Turkish citizen but the restriction did not apply to players already in Russia.
Turkish international Gokdeniz Karadeniz was able to stay at Rubin Kazan as the ban allows existing players at Russian clubs to see out their contract.
