The lesson for Pape Thiaw is that, in a tournament, form (and the fire of youth) can significantly raise your ceiling. Mbaye over Sarr would seem apparent enough now, but also be brave and play Iliman Ndiaye in place of Mane.
Lastly, we need to talk about Kalidou. A legend, and did well in a low-tempo first half, but when France turned up the wick after the break, he was badly exposed. Shame that Chelsea wasted Mamadou Sarr's time this past season, but it might not be the worst idea in the world to trust him regardless.
