Celtic frontman Leigh Griffiths has been urged to rid of his aggressive streak following his outburst last week.
The Scotsman lashed out at Hamilton's Sam Woods but was not punished by the referee.
And Celtic legend Charlie Nicholas believes Griffiths needs to ensure he focuses on his football rather than get caught up in on pitch scuffles.
He wrote in his Daily Star Scotland column: "Leigh Griffiths needs to stamp this anger out of his game. He was lucky not to be sent off at Hamilton on Sunday after putting his foot on Sam Woods’ chest.
"It wasn’t a forceful stamp but for me, he knew what he was doing. It was then his push on Woods’ team-mate Alex Gogic that got him booked.
"Why does he need to be so angry just now? He was angry with his goal celebration at Partick Thistle and when he had a go at Kris Boyd.
"I love when he’s on song and would like to see him back as Scotland’s number nine. Leigh will soon be 30 and he just needs to concentrate on enjoying his football.
"I retired at 35 and your playing days are behind you soon enough. Make the most of every moment and enjoy it for as long as you can."
Nicholas' sentiment has been echoed by Bhoys boss Neil Lennon who has encouraged Griffiths to work on his conduct.
He said: "That’s not a red card offence but he shouldn’t have done it. We’re very big on discipline here at the club and I don’t like to see things like that.
"It’s not a red card but he lost his temper. We need discipline at the minute. We can’t be doing with losing men on the pitch."
