Football has become a game that is now decided by the finest of margins since the introduction of VAR, so it is impossible to say whether Wolverhampton Wanderers goalkeeper Rui Patricio would have avoided injury during Monday's 1-0 defeat against Liverpool had the offside rule not been changed to accommodate video technology.
But as football searches for certainty and perfection, with every frozen frame being studied for the slightest infringement or every offside decision measured by millimetres, there are potential risks and consequences and the one fear that has been voiced by many within the game -- of an offside flag being kept down long enough for a player to be badly injured -- came to fruition at Molineux.
