And then there is Casimeiro, Fabinho, Bruno, Arthur and so on also competing for a spot at CM.
Luiz actually in contention despite most of these guys are available. Wes was brought in for a exhibition game and got 5 mins. Luiz is actually part of the real Brazil set up, him not being a shoe in at 22-23 really isn't a stick to beat him with.
And the Brazil squad isn't really that weak.
