Cristiano Ronaldo says "the heat of the moment" got to him in the incident that led to Manchester United dropping him for Saturday's game at Chelsea.
The Portugal forward left Old Trafford before the end of Wednesday's 2-0 win over Tottenham - for which he was an unused substitute.
"I've always tried to set the example myself for the youngsters that grew in all the teams that I've represented," he wrote on Instagram on Thursday.
"That's not always possible."
