Just thought I'd use this as a jumping off point to start conversation. The tactical aspect of your comments makes sense, but Jonas played against Korea while Veron didn't play at all due to injury.
I LOVED the fact that Pastore played any minutes during the Mexico match because it shows faith in him and I hope that he's the first winger/wide midfield off the bench if Maxi and Di Maria start, even though I'd rather have him start.
For the lineup, I want to see:
GK - Romero - looked very shaky for the first time this tournament. Had an early scare that hit the crossbar and a couple of harmless gaffes.
D (L to R) - Heinze, Burdisso, Samuel/Demichelis, Jonas - Heinze has been impressive and with all the young guys helping out, his experience can shine instead of his slow pace hurting the team. Burdisso with another quality game, Demichelis had no major mistakes, and Otamendi showed decent defense, but also little to no offense.
M - Pastore, Mascherano, Maxi - Mascherano is an obvious choice. Maxi has shown that he fits in with this free flowing offense. He's a solid complimentary player on a star-studded team and doesn't need the ball to thrive and threaten. Pastore is my choice over di Maria for 2 reasons - 1) Di Maria has sucked and has rarely shown his ability and more importantly 2) Pastore can play a more central role and join in the attack in more ways.
F - Messi, Tevez, Higuain - What a strike force. Messi is the underachiever of the group so far. Read that sentence again and tell me that isn't just prepostorously ridiculous. Higauin has been a goal machine (hey, someone has to knock in the cheapies), Tevez scored one of the best goals of the tournament against Mexico, and Messi has just been threatening to score every game and gives everyone a lot of space to operate.
This much I know about Germany - Lahm is tremendous, he's my 2nd favorite fullback in the tournament after Maicon and he's easily top 5 in the world alongside him, Essien, and the others (Dani Alves??) Schweiny is fantastic and the team runs through him. Otil or however you spell it a menace. Klose is threatening all time WC scoring records. Podolski shows up in big games. Oh, and their defense is probably the most organized, efficient, physical, and cohesive unit in the international footballing world. Needless to say, I'll be shitting myself thinking about them for the rest of the week.
For Argentina to win this game, their defense is going to have to defend with 6 instead of the usual 5 (Masch + 4D), and either Maxi or the other wing will have to track back. I expect to see the same strategy I predicted from Mexico from the Bavarians, counter out to the wings and put the pressure on Argentina through the air. If the D can hold, I'd like to see the offense run as follows: Higuain up top in the middle doing his thang. Messi and Tevez taking turns playing up top with him and coming back to receive the ball as a CAM and be the facilitators of the offense. I'd also like the offensive mids to help out in the middle when necessary and when not serving as a target, to get wide and stretch the Germans.
All in all, I expect a sick game.
