The Bayern Munich coach has reacted to the decisions made in rival BVB's defeat to Wolfsburg by calling for referees to be given help from their fourth officialsBayern Munich coach Jupp Heynckes has called for video evidence to be introduced after title rival Borussia Dortmund was on the receiving end of a poor refereeing decision on Saturday.
Marcel Schmelzer was shown a red card by Wolfgang Stark for a deliberate handball on the goal line, though replays showed that the ball had actually hit his leg as Jurgen Klopp's team lost further ground in the title race with a 3-2 defeat to Wolfsburg.
And Heynckes believes that decisions like those at Westfalenstadion could be removed from the game if referees were given more help from technology.
"For years now I keep saying the fourth official should sit in front of a monitor and tell the referee if it is no handball and no red card - like in Dortmund," he told Kicker.
UEFA president Michel Platini has said that bringing in goal line technology would be too expensive, but Heynckes does not understand why the footballing authorities are so against adapting the way the game is officiated.
He added: "It takes two or 10 seconds. I do not understand why there is such a lack of flexibility. They always say, 'It's not possible.' Of course it is.
"If a coach freaks out on the sideline, it is being communicated to the referee right away."
