Earlier this year, Manchester City midfielder Rodri issued a warning that players were "close" to taking strike action over their increased workload.
Rodri played 63 competitive games for club and country last season. But a recent report found that a player welfare 'red line' was a maximum of between 50 and 60 matches per season, depending on a player's age.
Some of the game's biggest names have joined Rodri in threatening to walk out, and the union that represents them is launching legal action against the sport's governing body, FIFA.
But there's a lot of money invested in football, so what's the likelihood the sport might change to stop players feeling over-stretched? And is strike action likely or even possible?
