Aaaaaaaaaannnnnnnnnnt.
Wrong.
Denying an obvious goal scoring opportunity by committing a foul is an ejection, he had angle and breakaway. In the box front and center of the goal.
Red card.
PK.
No. For example, if you take a shot and it hits someone's hand (and they don't overtly extend it with intent to block the shot) it's almost always a yellow. And we've already seen multiple times in this world cup someone get taken down in the box and given a yellow.
In this case, the Italian player was running full speed ahead and the Costa Rican cut laterally in front of him. There was significant contact, and you could've called a penalty and given a yellow. Personally, I'm glad he didn't get the call because he went to ground sooooo easily without even trying to keep his feet. Which is also I think why the ref didn't call it, because he went down so easy and the ref had a bad angle I think he assumed it was largely a flop.
But he didn't grab him or tackle, so there is no way in hell that's a red.
