Soroush just shut the f*** up will ya?
You entered the ground with f***ing headphones on? If I didn't know you, I wouldn't believe you, but I can easily picture you with your headphones on while playing and I too would want to punch you in the face.
Not that the dude did the right thing, but what's with this whole suing thing? If you got offended by his punch, you should've punched him back. That's how it's done everywhere in the world. Why be such a chicken shit?
Two things:
1. Grow some balls
2. Don't wear headphones when playing football with others. IT'S DISRESPECTFUL
