West Ham's Andriy Yarmolenko has called out Russia's silent stars over Ukraine - and mocked captain Artem Dzuyba's masturbation video in the process.
Yarmolenko went on to Instagram to call on Russia's national team players to show some "balls" and speak out about their country's bloody invasion.
But he kept his biggest criticism for Zenit St Petersburg striker Dzuyba, who was infamously dropped by his country two years ago after a video of him masturbating leaked online.
Ukraine winger Yarmolenko has family in his war-torn homeland and is on compassionate leave from West Ham.
He said: "I am Andriy Yarmolenko, a Ukraine national team player. I was born in St Petersburg but grew up in Ukraine and regard myself as 100 per cent Ukrainian.
"I have a question for the Russian national team players... Guys, why are you sitting like sh******s and not saying anything?
"In my country they're killing people, killing wives, killing mothers, killing our children. But you say nothing. You've given no comments.
"Tell me please, what will happen if all of you together, united, show the people what is really happening in my country.
"I know a lot of you, I'm familiar with many of you and you all told me it shouldn't be like this. That your president is acting incorrectly.
"So guys, you have influence over the people. Show this! I am asking you, please!
"I know some of you like to show your balls on camera but now the time's come to show your balls in real life.
"Thank you for your attention. Glory to Ukraine!"
Yarmolenko missed West Ham's win over Wolves at the weekend and will only play against Southampton in the FA Cup tonight if he feels mentally ready.
Hammers boss David Moyes revealed on Tuesday that the worried 32-year-old is "really upset" by events back home and spending hours every day on the phone to family.
Yarmolenko, who has also made a donation to his his country's armed forces, was also part of a joint video urging players, fans and coaches to "Oppose Russian propaganda" and "Stop the bloodshed."
Manchester City's Oleksandr Zinchenko and players from Italian sides Atalanta and Spezia, plus Ukrainian teams Shakhtar Donetsk and Dynamo Kyiv also participated.
It comes after Everton's Mykolenko also targeted Dzyuba in a comment direct to the Russia captain's own Instagram account.
Mykolenko said: "Whilst you remain silent b*tch along with your sh*****d football teammates, peaceful civilians are being killed in Ukraine.
"You will be locked in your dungeon for the rest of your life and most importantly the lives of your kids. And I’m glad."
Dzyuba eventually responded indirectly when another social media user called on him to answer, commenting: "All they can do is talk."
