The replays I've seen show the german take the guys legs and not touch the ball.
I see the same, he didn't touch the ball. Some say, he overdid the fall, ending in some kind of simulation, I don't think so...
that was not the only one... there is other where a german touch the ball which a hand...
I see that too, however there is also this time where Ayala grabs a german player (Ballack?), that was penalty too.
Another problem is that the referee gives a yellow card to Argentina's player for simulating the penalty, but when germany's player simulates (was Ballack again?), the referee didn't show any card to him, not even a yellow as he does to Argentina for the same action...
What bothers me was what happens with Abondazieri, he was supposed to be the key if Argentina ended in penalties, however he ended injured pretty bad, and the referee didn't show even a yellow to the german player who injury him, that was too much, I bet no one ever imagined that Argentina could loose their goalkeeper.
