I agree he wouldn't be a no-brainer choice for a pure man marker and it feels a bit wasteful to sacrifice what Dunga otherwise brings to the table. You would be tempted to say "let's stick Clodoaldo on that mission, he was a CB anyway and likely lower rated", or Di María as a less effective but more appropriate way to leave the midfield steady.
It is a credit to Dunga though that part of the reason to sacrifice him is the reading of the game/danger. That's why it's Charlton-Beckenbauer/Matthäus-Maradona, beyond adeptness at man-marking a major part of the job is having the requisite in-game intelligence to spot/anticipate how/where you may get hurt by the target.
It's also a credit to how you have set up. I can see that front four switching across 4-4-2, 4-3-3, 4-3-1-2, 4-4-2 ms and all aided by two GOAT fullbacks to boot so properly flanked whatever each asks from them.
I genuinely liked it a lot and I'm not exaggerating when I say in that sort of shape-shifting, with Pirlo orchestrating, Griezmann could have a game of Platini standards.
Robben's inclinations are more predictable, albeit problematic in their incisiveness. Park on the other hand, was not a player you planned for, not particularly creative so with a compromised Pirlo a bit meh, but in the alt scenario his movement was really clever and would go under the radar often, bringing a surprise element. I also rate Preben higher than probably anyone around here as well.
It's a great orchestra if you let Pirlo orchestrate so the name of the game is 100% stop Pirlo, period.
