I still can't see your point, Wouldn't be like telling any foreign player to go home?
If he said what is quoted it's not far away from telling a Pole, Indian or Jamaican (for examples) to 'go back to your own country and stop stealing our jobs'?
Gale is in a bit of trouble, less so for 'Kolpak' but I’m not sure you can claim in any context telling someone to go back to their own country isn’t racist
