During his time at Real Betis, Cardoso was a key player for coach Manuel Pellegrini, helping the team finish as runners-up in the UEFA Conference League. Atlético de Madrid praised Cardoso for his ability to balance the team's play and create attacking opportunities.

Cardoso was born in the United States, but holds Brazilian and Italian passports, making him eligible to play in the EU. He has represented the United States in 22 international matches and participated in the Gold Cup.

Cardoso will be presented as a new Atlético de Madrid player upon his return from holidays in Brazil. He is the fourth signing of the summer, following Matteo Ruggeri, Álex Baena, and Thiago Almada.
