With Jose Mourinho set to lock horns with Jurgen Klopp on Thursday night, the Tottenham Hotspur manager seemingly took a swipe at the German regarding his recent touchline behaviour.
Mourinho himself had exchanged heated words with the Liverpool boss after the final whistle of a dramatic 2-1 win for Liverpool six weeks ago.
The Portuguese tactician later complained that Klopp seemed to get special treatment despite his animated behaviour on the sidelines.
The former Borussia Dortmund boss was in the headlines again after the Reds' 1-0 loss to Burnley last week, with Klopp and Sean Dyche having a go at one another in the tunnel at half-time.
Speaking ahead of Spurs' clash with the Merseysiders on Thursday night, Mourinho could not resist pointing out the lack of punishment for those actions.
"In my case, I felt an evolution. I felt an evolution on the emotional control," he said, per the Metro.

"I felt an evolution in that the calmer I am, the better I can read the game. And I'm even happy that my assistants, they look to the touchline sometimes for communication and I stay in a privileged position.
"And I felt that I had to change my behaviour, which I'm really happy with. That's my personal case. I cannot speak for other guys.
"What I can say is when I didn't behave well, I paid the price. And I paid the price in two ways: one was to see matches on TV in the dressing room and another price was big-money fines, and I feel that, for some of the other guys, it doesn't happen the same.
"It doesn't happen the same with them. But, if the referee and the fourth official are there to do that job, I just hope they do that job and act the way they have to act."
