Olympiacos test negative for coronavirus after wolves concerns postponement of man city vs arsenal
I think there may be some confusion here!
Olympiacos is a Greek football club, and Wolves (Wolverhampton Wanderers) is an English football club. There is no connection between the two teams that would lead to a postponement of a Manchester City vs Arsenal match.
Additionally, Olympiacos has not tested negative for coronavirus, as there is no reported connection between the team and the virus.
It's possible that you may be thinking of a different match or situation. Could you provide more context or clarify what you're referring to? I'd be happy to help if I can!
