UCL talking points: Mbappé's PSG legacy? How did Madrid win?

The 2023-24 Champions League semifinals are all wrapped up with plenty of drama, an upset and heartbreak. Borussia Dortmund delivered the final blow to beat Paris Saint-Germain on their own ground in France, leaving Kylian Mbappé without a European trophy as he prepares to make his exit at the end of the season. Elsewhere, Real Madrid did what Real Madrid do and stunned Bayern Munich in the closing stages of the game to seal their spot in the final. In the final, we'll see Dortmund take on Madrid, but before that we asked ESPN writers Gab Marcotti, Alex Kirkland and Julien Laurens to answer some of our burning questions from this round.
