well i found this picture on net, can someone explain it? not sure if photoshop or just...

?

This is fake if Barca had 12 men in the pitch one of the refs would have spotted it. Not to mention refs normally count the players before each half begins. I watched the game and there were 11 players, 10 after the red. 

It's definately photoshopped.

Looks Like 5 and 9 is the same person(iniesta)

hm yeah i agree with don.

but number 5 is standing while 9 is running.

Obviously it's photoshopped. It's ironic you put that picture because the way Barca play their football, it's like playing against 12 men.

quikzyyy exactly; it's Iniesta running at one time, put into the photo, with the other Iniesta standing from another minute.
