Very few people would expect a regular football match - with an open invitation for all to take part - to be thought or seen to be a fair contest, when the referee judged it to be acceptable for them to also play in the game as a participant.

Perhaps in order for this to be seen to be a fair game - they may expect this referee to make a choice to either be a referee or to be a player? Especially when they started sending other players off for what they judged to be unfair play.

Even without the referee wishing to play both roles - most people would be surprised that such a game of football would ever get completed - if this referee kept trying to change the rules, in order turn it into a game of rugby. And tried to exclude some players from the pitch altogether, whilst trying to pursuade the rest of players that this change was a far better idea than the original concept.

It would not be too much of a surprise if this referee was not asked or expected to play whatever game they wanted and by whatever rules - but to do this elsewhere and to leave everyone else to get on with their football match.
