#1 The hand-ball equalizer

Southampton started their away game at Watford brilliantly to end the first half with two massive goals from James Ward-Prowse. However, the men in yellow drew level in the second half and clinched a draw for themselves in the 90th minute of the game.
Did Southampton squander their lead or were they robbed off two well-deserved points?
In a desperate attempt to make something off the match, Abdoulaye Doucoure scored a goal in stoppage time to salvage a point for the hosts. However, a replay of the goal displayed a clear handball from the Frenchman.
The error cost the Saints a crucial victory away from home and understandably, the fans are furious with the refereeing, or lack thereof, for the goal.
This incident raises the pertinent PL question yet again: when will the VAR be introduced in English football?
