You misspelled Rui Costa.
If you are going with that formation under no circumstance whatsoever does Zidane not start as the #10 but good to see you back at your snake oil salesmanship best.
Firstly, independently of him being my player, as far as 90s Serie A is concerned, Rui Costa was IMO a better and more consistently influential performer. He just didn't play for Juve or France. Zidane is the better and more successful player over the course of his career, obviously.
Second, in that side with Del Piero
and Brehme he is a better fit, not just because his favoured left/IL channels are well taken care of, but particularly without knowing who the other midfielders are.
Zidane had a setup that allowed him complete freedom in a dominant team, while Rui Costa had to adapt between being a free #10 or dropping very deep to orchestrate the transition.
In Juve's lopsided setup without a particularly expansive leftback I'd take Zidane though. Different #10s, horses for courses and all that, in what is a comparison of fine margins (but hugely relevant given the importance of the role to the team and it's functioning).
