At MLS Media Day on Saturday, Laurent Ciman made it known he'd tolerate no fraternizing with the enemy.
After catching LAFC teammate Carlos Vela in conversation with the Galaxy's Giovani Dos Santos, the Belgian defender reacted quickly to pull Vela away saying "don't speak to him" as Dos Santos protested.

The move was all in jest, as both Vela and Dos Santos laughed off the incident. But just in case, Ciman took to Twitter to be sure people knew he was having a laugh.
I want to reassure everyone. it was just for laughing. i like @OficialGio— Laurent Ciman (@LaurentCiman23) January 20, 2018
