Matchgoers can find and tag themselves on the giant photo using their Facebook accounts. They can also see which of their mates are tagged and invite other friends who were at the game to join the fun.
Loads of fans who weren't at the game have also taken part by clicking the 'Wish You Were Here' option and adding their profile pic to the virtual stadium. The first 1,500 to do this will be added to the Kop.
We're also giving you the chance to win some great prizes.
