Crystal Palace manager Roy Hodgson says it is difficult for emotions to be controlled in a game situation amid calls for Premier League players to stop celebrating goals.
Referees in the top flight are to warn captains "the eyes of the world are on us" in pre-match meetings after celebrations continue to occur in the division.
Premier League chief executive Richard Masters wrote to all 20 clubs on Tuesday reiterating the importance of adhering to new, stricter coronavirus protocols.
In the wake of several outbreaks at clubs and a number of postponements, players have been told to avoid hugging, handshakes and swapping shirts, but Hodgson has sympathy for them.
Ahead of Palace's trip to Arsenal on Thursday, he said: "The tension, stress and anxiety of the game, you look at the managers on the touchline and you can see anxiety etched on their faces.
"It's difficult to push all those emotions aside when something happens and put on your Covid head and ask how far apart are you?
"I just think it's a very very difficult thing to deal with and I don't have the answer to how we deal with it, I really don't.
"I'm open to suggestions about when a player scores a goal, but what are we going to do when players get into a huddle? To be quite frank, I don't think I've seen a goal that I can remember where players haven't celebrated, so I don't know what the answer is.
"I think some of the other things that the Premier League are keen to stop with the new protocols, with regard the training ground and the canteens, they are easy enough to follow and I think it's good that we follow them.
"But when the match starts, stopping the celebration, stopping a manager shaking hands with another manager after games gets forgotten."
