Well, you'll find out tomorrow, then.they told me they cannot know! how i can be sure!
You're outside the camp nou, so go to the tickets office and ask.
In ticket office they will not be able to confirm if it is fake or not, have just asked them yesterday. The only way to check it is at stadiums gates.
There were still tickets available yesterday why would you buy them from a dude on the streets for 500 euros?
