Kepa must respect Sarri's decisions – David Luiz

David Luiz believes Chelsea's Kepa Arrizabalaga should have respected Maurizio Sarri's decision to take him off in the EFL Cup final, but called the incident "normal".

Chelsea lost to Manchester City on penalties in Sunday's final at Wembley but the drama came at the end of extra time, when Kepa refused to be substituted after he had gone down for a second time with what appeared to be cramp.

Sarri reacted furiously to Kepa's defiance, charging towards the tunnel before returning to the touchline.

Both Kepa and Sarri attempted to play down the incident following the final whistle, insisting that it was a misunderstanding between the player and coaching staff.

Maurizio Sarri says the Kepa substitution confusion was 'a big misunderstanding' because he thought the player had cramp. However he says Kepa was right that he could continue although the way he went about it was wrong. Sarri says he needs to talk to Kepa now. #CHEMCI

And although Luiz claimed to have told his team-mate that the coach's decision had to be respected, he reasoned that, in the heat of the moment, it was difficult for both parties to get their points across.

"I don't know. I think, I don't know," Luiz told reporters when asked if he knew why Sarri wanted to change goalkeepers, with Willy Caballero having been ready to come on.

"The coach wished to do the substitution not because if he had an injury or not, but he didn't understand that and just then he's good and he was feeling ok.

"In the game sometimes you don't have much time to explain things. It's ok. It's normal.

"I just said to him the respect goes to the decision of the coach, but I didn't know if the coach wanted to change him because he was feeling some pain or because it was his decision, so I don't know."
