Luiz was angered by Aguero's nasty lunge during Sunday's FA Cup semifinal.
I've contacted @davidluiz_4 and apologized for what happened during the match. It was an impulse reaction that shouldn't have happened.
And Luiz replied:
Thank you @aguerosergiokun for a demonstration of character. We get to know great man and athletes this way.
