Manchester City's potential punishment remains unclear after the Premier League champions were charged with allegedly breaching more than 100 financial fair play regulations, but relegation is one of the potential extreme measures.
It is certainly the preference of some others within the English top flight, with calls for the champions from the last two seasons to be kicked out of the league if the charges are upheld by an independent commission. Things could get complicated, though, with no guarantee of a team expelled from the Premier League in these conditions being accepted by the EFL.
If City are found guilty and forced to play in a lower tier, they would not be the first team demoted after being punished for breaking rules. Here, Mirror Football looks at some other examples.
