Why are players forbidden to take off their shirts to celebrate?

Yes, if you take it off, you have to wear it. Procrastination is the most correct way.

However, 1999 seems to be detachable. At that time, players often took off their coats and saw slogans on their underwear, many of which were related to political and racial sensitivities. If the Football Association is scared, don't take it off. That's it. Give points. What is official is all official languages, which is not the most important point.
