Marchisio had his knee raised in response to an oncoming collision, Rebic had his leg out-stretched. Therefore, the latter is clearly worse.
So you're telling me he didn't hit the players leg with his studs?
In Marchisios situation, it was clearly worse to have his knee raised instead of keeping the foot down as you can (if you're not blind of course) can see in this video
It's really pathetic not to admit it was a red
edit: an actual comment from an ITALIAN on the video
"Everyone saying it's not a red card is stupid as hell. I'm italian. It was a red card offense. You never pick your boot up ever when committing a challenge. That's malicious intent no matter how you look at it. Marchisio did it INFRONT of the ref. stupid. Red card. As for the Suarez incident. The referee didn't see it. You can't pull a red card based off players suggestions. If he didn't see it, too fucking bad. Either way, fuck Uruguay. Suarez is a piece of shit."
Is it really that hard to understand studs against leg is ALWAYS a red, no matter what? Is it really that hard?
