Mendes is the one that sits back and forms the back 3 most often, his runs forward are targeted, efficient and impactful, unlike balde who is just always running.
He's more kounde than balde is that sense, but better offensively.
Balde is the hakimi of the team.
Pacho doesn't really cover for him, when he goes forward.most often a Midfielder comes in to form the back 3.
