"Cristiano's reaction is natural, but it is not acceptable for a national team captain," he told Record.

"He cannot throw the armband on the ground and go to the locker room while the game continues. it is not acceptable for a player of his importance.

"I understand his frustration and I agree with him because his goal was valid, but the referees have to make decisions, without VAR, and he has to set an example.

"The example he set last night wasn't good enough."

On Sunday, Ronaldo took to social media to address the criticism he faced for getting rid of his captain's armband in dramatic fashion, insisting that leading his country is one of the "greatest honours and privileges" of his life.
