2021: The latest teenager to swap Brazil for the Bernabeu, Madrid paid €35m in January 2020 to sign the Flamengo playmaker, who had been likened to Kaka in South America. In the summer of 2020, he joined Borussia Dortmund on a two-year loan deal, but was struggling to make an impact in Germany.
2022: Things did not improve for Reinier, as the Brazilian started just once in the Bundesliga during his second season at Dortmund, and he was sent on loan to Girona upon his return to Spain in the summer of 2022.
2023: Injuries kept Reinier on the sidelines for much of the first half of the 2022-23 season, and he made just five starts in La Liga.
2024: Reinier is spent the following campaign on loan at Serie A side Frosinone, and though he made an encouraging start to life in Italy, his form has dropped off as the club suffered relegation.
2025: Out on loan again, this time with Segunda Division side Granada, Reinier has mostly been a starter, though recently suffered an injury.
