During TOTY I was able to craft Luiz whilst I was trying to pack a TOTY. But the reality is I have to do some work to get him into my team.
Long story short:
SIF Varane, with 8 chem Luiz, plus any icon keeper.
SIF Varane, with full chem Scream Pique, plus the GOD Nominee Ter Stegen.
Is Luiz that much of an upgrade on Pique that you can lose Ter Stegen?
