VAR - what happened next with these World Cup moments?
Video assistant referees took centre stage in Tuesday's Carabao Cup semi-final first leg between Tottenham and Chelsea.
Spurs' Harry Kane scored the only goal of the game with a penalty, awarded after VAR decided Kane was not offside before being fouled by Chelsea keeper Kepa Arrizabalaga.
We will see more of VAR next season, when it is set to be used in the Premier League.
Can you work out how these five refereeing incidents - which could all have been referred to VAR - ended during last summer's World Cup?
