In 2016, Liverpool's manager banned his players from touching the famous 'This is Anfield' sign before taking to the pitch - until they won a trophy.
Jürgen Klopp is clearly a man who respects tradition - he needs to at a club like Liverpool, one steeped not only in tradition but superstition and ritual.
But three years ago he banned players from touching the fabled 'This is Anfield' sign as they emerged from the tunnel and out onto the pitch - the ban, he explained, would be held in place until the team won a trophy.
It was Bill Shankly who had the brainwave of placing a sign in a place where both the home players and the visiting team could see it just seconds before they stepped out onto the Anfield pitch.
For 42 years, Liverpool players would perform the ritual of touching the sign as they made their way out onto the pitch.
That tradition came to an end three years ago on the coach's orders and only resume once they added some new silverware to the Anfield trophy room. "I've told my players not to touch the 'This Is Anfield' sign until they win something. It's a sign of respect," Klopp told The Times in April 2016.
Jordan Henderson and Gini Wijnaldum were the only two Liverpool stars to touch the famous 'This is Anfield' sign before the Reds' victory over Norwich.
Despite the new rule change at Anfield, Klopp decided against showing off the Champions League trophy.
“Nobody told me I have to!” he said when asked why they didn’t bring the cup out. “I touched the European Cup on the (CL final) match day and the day after, since then not.
“We are now in the new season, and I don’t have to think about that anymore.”
