The Argentine forward has taken to Twitter to admit that he has contacted his South American counterpart following their clash in the semifinal meeting at Wembley
Aguero caught the Brazilian with a high two-footed tackle in the Wembley clash, which the Premier League champions won 2-1 thanks to a goal from the Argentine and another from Yaya Toure.
However, their success has been somewhat overshadowed by the furore caused by the incident, for which Aguero received no punishment from referee Chris Foy or from the FA's disciplinary panel.
The 24-year-old has moved to bring an end to the fallout, taking to his Twitter account to admit his regret for his actions.
He tweeted: "I've contacted @DavidLuiz_4 and apologized for what happened during the match. It was an impulse reaction that shouldn't have happened."
