"For the moment the criteria means it is absolutely difficult to say that we can play competitive football and believe me I regret it profoundly because I am a football man.
"I am a little bit afraid that to have a complete solution we will have to wait until we have a vaccination programme, but I think the time has come now to think of some hygienic rules.
"For instance to avoid spitting - why do we have to see that in football and not in other sports? This is one of the things we have to consider because this is a real danger in the future."
