Diego Carlos became an Aston Villa player in June 2022. Carlos made his Villa debut when he started against Bournemouth on the opening day of the 2022/23 Premier League season.

However, he ruptured his Achilles tendon just a week later in only his second appearance for the club, requiring surgery before starting his rehabilitation and road to recovery. Carlos worked his way back to full fitness and made his comeback against Wolves in May. 

The Brazilian joined after a successful stint in Spain with Sevilla, where he became a Europa League champion. The defender made over 100 appearances during his time in Seville, helping the club record three consecutive top-four finishes. Carlos made his name at Estoril and Nantes before his move to Spain.

On the international stage, Carlos won an Olympic gold medal at the 2020 Games in Tokyo. The Sao Paulo native was a mainstay of the team alongside fellow Villan Douglas Luiz as the Seleção progressed through the tournament unbeaten.
