After David Luiz was seen talking to goalkeeper Kepa Arrizabalaga when the latter refused to be substituted during his side's Carabao Cup final defeat, the Chelsea defender has since revealed what he told his teammate in that moment.

Arrizabalaga, who is the Blues' record signing, picked up a cramp in the dying minutes of extra-time, with the game against Pep Guardiola's Manchester City still tied at 0-0.
However, he refused to be replaced by Willy Caballero despite coach Maurizio Sarri wildly gesticulating for him to come off from the touchline.
Luiz, who was seen chatting to the shot-stopper during the confusion around the non-substitution, has since revealed that he was telling the goalkeeper to listen to the manager.
"I told him to respect the decision of the coach," the Brazilian said, as quoted by the Daily Mirror.
None of Chelsea's other senior players intervened, though, with many questioning why, in particular, Blues captain Cesar Azpilicueta did not assist his coach, but the Spaniard later insisted he was too far away from the incident.
"I don't know about this because I was on the other side of the pitch on this incident," he said, according to the Mirror.
Sarri, though, has since explained that the situation was just a miscommunication between him, his goalkeeper and the club's medical staff.
"In that situation, there was a big misunderstanding caused by the radio," the Italian tactician told Sky Sports.
"I understood there was a problem and we needed a change. I didn't find out until the doctor arrived to the bench after a few minutes.
"It was a big misunderstanding. I understood the goalkeeper had cramp and, for me, he was unable to go to penalties, but the problem was not cramp so he was able to go to penalties."
Chelsea lost the ensuing penalty shootout 4-3, with Luiz and Jorginho missing their spot-kicks.
