There's an interactive heatmap on here:

I can't figure out much from the heat map what the formation was, at times looked like 433 but also looked like a 442 at times too.
Indeed, but it's a bit beside the point as regardless there are plenty of teams who use wingbacks in a 4-3-3 or 4-2-3-1, including Real Madrid throughout their season. They set up officially in a 4-3-3 yesterday, and regardless of where there players ended up throughout the match due to team counter tactics or individual player movement, the point is that wingbacks are very much used in such formations.
Whether or not he wants to point out individual players in the squad that he wants out is another thing altogether, but the entire thing that spent way out of whack was his misinterpretation of a very simple, single counterpoint.
