I have to add, however, to a point that consortium made:
David Luiz (my Man of the Match in Brazil's two previous games) really let Brazil down in a big way. Consortium was absolutely right; Luiz played more like a forward than a defender, rushing up to try to create opportunities, and leaving giant holes behind him as a result. Brazil seemed completely incapable of marking anyone, affording Muller and company all the space they needed to get into position.
My speculation is that Scolari's plan was to come out striking hard and put Germany off-balance; however, Fred and Hulk simply lack Neymar's speed and prowress, and Brazil was completely unprepared for Germany's counterattack. Brazil simply could not, or would not, adapt to being down, and that was what I think ultimately led to their downfall.
Luiz simply reverted to type.
Gary Neville once infamous described Luiz as playing like as if he was being controlled by 'a 10-year-old on a PlayStation' and that's what we got today. Luiz is clearly a talented player; hardworking, brave, strong and powerful with the ability to deliver dangerous long balls and go on charging runs that most defenders lack. The issue is that he lacks discipline and gets rushes of blood to the head. In other positions taking the low percentage option can be an asset because the rewards outweigh the risk; if an attacking midfielder shoots from range rather than passes to a teammate then the risk of it not paying off is simply a missed chance, the reward is a goal. But if a defender does something equally risky then the equation goes the other way; the reward is simply to break up and attack or bring the ball out of defence quicker, the risk is a goal being conceded.
Mourinho isn't the most popular of managers and people often tend to criticise what he's done. But this World Cup has proven him right on at least two grounds. First his decision to drop Casillas for Real Madrid (something Ancelotti has kept for all but cup games... and Casillas nearly cost them the Champion's League) was pretty much vindicated by yet another pair of inept Casillas performances in Spain's first two matches where he was a large part of them going out. And now his decision to primarily use Luiz as a midfielder rather than a defender (unless he really has to) has been given a lot of support by this match.
On paper Luiz would actually be pretty effective as a deep lying midfielder. His workrate and strength means he'd harry opponents to win the ball back... and while his discipline may be limited in midfield he can balance that out with eagerness more than a defender can. It also plays to his strengths in that he would get more chances to go on those driving runs and deliver those deep balls. The question is whether he'll actually ever be given the time in that position to develop his knowledge there; being a defender who occasionally cameo's further up the pitch isn't really the way to do it.
I think his issues may end up being exacerbated by being at PSG. While PSG may be a top team with a large number of exceptionally talented players, Ligue 1 isn't. There's PSG, a bit behind them there's Monaco, below them there's about four teams and then there's a lot of dross. Put simply he won't have
to be that disciplined to still do a good job as a defender there and considering that most teams look to sit back and hold off PSG he'll be even more encouraged to start breaking forward and leaving gaps behind. Moreover, despite his price tag he's not going to be the leader of the defence there and thus have to take on more responsibility... for the moment that role belongs squarely with Thiago Silva. That may offer the one silver lining... as things stand PSG have both the present of the Brazilian defence (Silva) and the future (Marquinos) on the books, which means Luiz will get to play with them week-in, week-out and hopefully develop a good understanding.
