Atletico Madrid captain Immediately made a thinly veiled dig Real Madrid star Thibaut Courtois.
Los Rojiblancos took a derby draw with Real Madrid in dramatic surroundings at the Estadio Metropolitano.
The hosts hung on in the closing stages as they eventually grabbed a draw on a night of great controversy.
The game was temporarily suspended in the final stages after problems in the area of the arena that hosts the ultras of Atletico Madrid.
Diego Simeone and Koke both went home to call for calm with supporters angered by Courtois' celebrations after Real Madrid's opening goal.
Former player Courtois has been a consistent villain for his former fans, and was pelted with lighters and other objects, before the game was stopped by match officials.
Koke was asked about the view on the row at full time and was clear about the need for experienced players to keep in control.
“It was a tense moment. But this cannot happen in a football field. We are professionals and we have to know where we are and be smart, but other incidents cannot happen”, as quoted by DAZN, via Marco.
“The players have to be smart. The protocol said that if the incident was repeated, the match would be over.”
Atletico Madrid are next in action on October 2 as they head to Benfica in UEFA Champions League action.
