Kante is a dream for a team that has a lethal attack already in place (with at least one really good creative attacking midfielder) because the man is not playing an incisive forward pass. Or really any pass forward. When he can focus on making the middle of the pitch hell for opposing players he's sill one of the best in the world. He did a good job of that today.

Unfortunately for the team, the shitty attack needs the midfield to progress the ball forward as soon as possible to allow them to operate in space. And that's just not happening. As you said, he's not being helped by the other two midfielders in that regard. That area must be the priority to improve in the offseason. Or, with the newfound defensive stability, try the 433 again and let Mount be the 8.
