It is "frankly not comprehendible" that professional football is continuing in Belarus amid the coronavirus pandemic, BBC reported referring to world players' union FIFpro.
"We're appealing for it to be taken with the same cautionary measures that have been taken in the rest of football," Fifpro general secretary Jonas Baer-Hoffmann said. "It is frankly not comprehendible how this could be going on.
"Why those standards there would be looking so much different from just across the border, I don't think anybody can explain. So everything in common sense tells you that they need to apply the same standards and we will be lobbying to that effect.
"Yes, there are players who are reaching out who are concerned."
The Belarusian championship is the only one in Europe that has not been suspended amid the pandemic.
