A Russian footballer has caused controversy by revealing a T-shirt showing Vladimir Putin's face after a European match in Istanbul against the Turkish side Fenerbahce.
Dmitry Tarasov, a midfielder for Lokomotiv Moscow, took off his football shirt to show a vest with a picture the Russian President wearing navy uniform.
Below the picture was printed the phrase "The most polite president".
Fenerbahce won the match 2-0.
Tensions between Russia and Turkey have been high after Turkish forces shot down a Russian jet in November allegedly in its airspace.
Russia's support of the President Assad regime in Turkey has also caused relations to suffer between the two.
Following this incident, both Mr Putin and Turkish President Tayyip Erdogan have been sharing angry words ever since.
Tarasov defended his actions in an interview with Russian news agency, R-Sport: "It's my president. I respect him and decided to show that I'm always with him and prepared to give my support."
"What was written on that shirt was everything that I wanted to say."
