Does running with a mask like that do not interfere with the breathing of the players, if indeed it is official?
It surely will, especially if it's a fully protective masks with no breathing holes.
As said above it could probably be intended to be a joke, but if football is to resume early, the technical crew, players in the bench and other non-playing staff my need to put on adequate protection, and customized ones to the teams design could be used
I wonder if it would be easy for the players to play football with masks.
It would be very hard to breath with them and it might have negative impact to their performance due to the limited air that will be flown to their lungs. It is a good solution for protection to those who are sitting on the bench though.
