Pretty sure 10km in the air was considered safe a week ago.
Fair enough, but to be honest and to invoke a blatant stereotype, South American players in Ukraine face more danger from racism than from the war.
So a player who feels seriously threatened by racism and whose team's city is now a warzone "doesn't have a leg to stand on?" Wanting to get out of there sounds pretty valid to me, even if the latest developments in Ukraine were just the straw that broke the camel's back.
But they aren't going to live or play in Denetsk, they will be in the stable parts of Ukraine. These places are different to what you expect, the whole country isn't a war zone just a few provinces.
I've been within a couple of hundred of KM's of Grozny and while security is higher than normal the cities in the region themselves are safe enough.
If they were forced to play in Denetsk or live there then you have a point but they will be playing (and I assume staying) in safe zones.
If they were woried about racism they shouldn't have signed up to a team in a former soviet republic. It kind of goes with the teritory to be frank. Stein obviously had one look at the place and decided it wasn't for him and left.
