Clear as day.
Kounde has one player centrally in front of him, and one player on the side. He positions himself to be able to intervene to both, but prioritizes the central player, as he should.
Meanwhile, centrally, the situation is reversed. We have two players (Garcia here is marking Sorloth), in charge of blocking just one AM player. It is pretty clear the CB pair, having numerical superiority, 2 vs 1, should have handled Sorloth.
It's funny. You slam the player dealing with 1 vs 2 situation, and not a word about 2 players who got folded by the one threat they should have covered.
