Mbappé and Álvarez bring superhero vibes but La Liga sidekicks pack a punch | Sid Lowe

Sunday was their day, all set up that way, everyone at it. It had taken seven years for Kylian Mbappé to arrive at Real Madrid and €75m for Julián Álvarez to turn up at Atlético Madrid. They had been presented, 110,000 there just for that, a bit of waving and a word or three; now, they would actually play. Mbappé, the man they call the turtle, with the features of Donatello and his mask too, and Álvarez, the striker whose brother Rafael called him the spider when he was four because he seemed to have a lot of legs, a nickname which has caught on, wearer of a mask of his own.
