Sorry mate, but it's precisely the arrow to the centre I have a fundamental problem with. He wasn't a holding midfielder. Outside halfbacks were either the same as fullbacks when they had no attacking game or more like modern wingbacks/wide midfielders when they did (a diamond would really suit them actually). The difference in roles is significant.
Think about it, the oppo also played five forwards:
------------Inside Right--------------Inside left
Outside right------------Centreforward-----------Outside left
vs
-----Left-half----------Centre-half----------Right-half
--------------Fullback--------------Fullback
Now, the fullbacks will naturally pick the centreforward and you want one spare for cover. The left-half's detail clearly is the right winger and the right-half's the left winger, while keeping an eye on the space between CF and Outside R/L, which was bound to be attacked by the Inside Forwards. When the play is on the opposite wing they will tuck in and be more mindful of the inside forward than the winger (typically somewhere in between to have time to react either way). That's almost to a T what a fullbacks' defensive job is today.
Now the centrehalf is a completely different player and more akin to the modern DM type you are looking for. The cover requirements at the back mean he is technically outnumbered here: there's no No.10 man-marking mission like a Makelele would do but instead he has to pick up the inside forward closest to the action, keep the shape and if he gets the ball shepherd him into a cul-de-sac out wide or, even better, disposses him.
It's a completely different job, the space to cover, the positional awareness required, it's all completely different and you would know it from seeing the countless experimental midfield arrangements we've had over the last few years. Phil Jones anyone? He makes a decent fullback but is all over the shop when played as a central DM.
I do think Andrade had the requisite awareness, but he is completely unproven in the lone central role and in an all-time draft where anyone can be picked that's fecking criminal, particularly when the other two stellar midfielders clearly called for a holding one so they could have greater freedom to do all the damage. You didn't need Andrade's damage. If you want the best out of him you want him as a wide midfielder, but then you are paying a disservice to one or both of the others (which is where I disagree with
@Chesterlestreet, as he says, Matthäus is a complete midfielder who can do almost anything so I'd rather sacrifice him a bit asking him to contribute defensively to release Didí from a duty he was notoriously averse to, Zito performed a level of heavy-lifting Andrade is unlikely to provide here).
Unless you got a horrendous draw, you should be fine anyway. It's not exactly a disaster, it just means getting a bit less than the sum of parts in what is a very strong unit anyway.
Yeah - see above.
