Hugh Dallas expects Scottish referees to take a different approach to handball under Willie Collum next season.

Experienced grade one official Collum will replace Crawford Allan as the Scottish FA’s new head of refereeing.

Handballs caused controversy in the Scottish Premiership last season, with managers citing a lack of consistency.

Dallas, who has a referee training role in Turkey and previously held similar jobs at the Scottish FA and in Greece, was asked if Collum’s appointment would bring a change and said: “For sure. Handball has been a big issue. It’s down to the instruction that referees are given in any country.

“We’ve not had a big problem in Turkey with handball because we’ve told the referees this is what’s required – raining balls, as we call them falling out the sky on to arms, don’t touch them.

“I don’t know what the referees have been instructed in Scotland regarding that. Willie Collum’s already had meetings with the referees and according to what I’ve heard, it’s been really positive.

“Willie will take the referees with him. They’ll all sit round and they won’t be dictated to and told, ‘this is what we want’. It’s important that referees all agree when they leave the room what the interpretation of handball will be.”

Dallas believes it is important to keep the interpretation of the rule “simple”.

“One of the words that we use out there is impact. If an arm’s clearly out and it’s impacted on the ball, the direction that the ball is going in, maybe the other team has benefitted through that, that should be punished.

“If the ball is going towards the goal and the arm is out and it hits it and you think, ‘where was that going? It was probably going towards the goal’, it’s difficult not to punish that.

“If you keep it simple, then you’ll definitely have more consistency.”

Dallas also revealed the idea of giving managers two VAR challenges during matches “is being floated” at International Football Association Board level.
