He made a meal of it AFTER the goal was awarded, not at the time I agree. Nothing "clever" about the push though IMO, and we've all see far worse go unpunished in the penalty box.
Add me to the list of people who consider that a perfectly valid Swiss goal. That nudge in the back was trivial, it wasn't like the striker was all arms and elbows all over the defender, and I also felt the defender made an absolute meal of the fairly minimal push in the back.
Also, Brazil...
