Last week on social media, Theo Walcott was saying how much he loved the back-bump celebration with Per Mertesacker after an Arsenal victory.
It has become somewhat of a post-match ritual for the two Gunners stars following a win, but Per Mertesacker was not involved in the 3-1 FA Cup third round success over Sunderland.
That was not a problem for Walcott as he picked a supporter out of the crowd and took him on to the pitch to replace the German centre-back.
