Suddenly, there was Kylian Mbappé. With 45 seconds left, at last he found a way through and the solution that PSG had sought all night. Dashing between Lucas Vázquez and Éder Militão he dropped the shoulder and slotted a superb shot into the net to secure a victory that had appeared set to evade them, this place erupting. They had waited all night for this but it had been worth it, and the win had been deserved. It took 22 shots, including a penalty that Messi saw saved by Thibaut Courtois, but they had finally done it. And it had to be him, the man who had started it all ending it too.
