“We need to ensure they are protected.

“I understand there is a maybe a dimension of ‘you have to get tight to Scott Sinclair, got to put in a challenge to Kieran Tierney or James Forrest or whoever’.

“But it is the responsibility of the referee to protect the game and the players because I said it was an horrendous challenge and the week before against Inverness Scott Sinclair had an awful challenge on him.

“If we are trying to get the best players playing here in Scotland they need a little bit of protection.”

“We are a team of men. We have young guys in the team but we are playing a man’s game so we have no problem with the aggression and we have coped with that at places like Aberdeen in a really tough physical game, tough challenges, fair challenges.

“The concern for me is the challenges that are late, that like last week was a straight-leg challenge which could have really damaged him.

“If Kieran’s foot was planted you could be talking a different story about one of the great talents in Scotland.

“Now that is the duty of the referee, to protect them and protect the game.”
