Chelsea manager Mauricio Pochettino wants to discuss his team's ill discipline.
The Blues have received the most yellow cards of any team in the Premier League so far this season.
A game on Sunday against Brighton saw them receive a red card for Conor Gallagher, while Reece James received a red for two yellows against Newcastle United.
We were talking in the meeting and I showed the players clips of the yellow cards," Pochettino told club media.
There have been too many. The rules have changed this season. We touch the ball from here to there and get too many yellow cards. That is a tic we need to change. We need to be clever.
You upset the referee and you get a yellow card, and then in an action that can happen during a game, you can receive another yellow card. We have received too many yellow cards like this.
We were talking about Nico Jackson and the yellow cards were for complaining to the referee. The opponent made the foul, but didn't receive a yellow card. You complain why not, and you get a yellow card. We need to be clever in improving this area because we cannot be silly and repeat the same mistakes."
