Real Madrid won the most recent Champions League final, defeating Liverpool 1-0 in the 2021-22 final held at the Stade de France in Paris on May 28, 2022. Vinícius Júnior scored the winning goal.

However, since my knowledge was last updated in April 2024, there may have been a more recent final if you're asking about the 2023-24 season or later. Could you clarify which season you're asking about?
