Fourth round, 30 October 2012, Madejski Stadium
An incredible match, the joint-highest scoring EFL Cup tie in history, and it took extra-time to find a winner.
Still without a win in their return to the Premier League, Reading threw away any joy their fans were feeling as they led Arsenal 4-0 by capitulating to lose 7-5.
Arsenal found themselves four down after 35 minutes, but Theo Walcott’s goal before half‑time sparked a comeback that dragged the match into extra-time.
Marouane Chamakh put Arsenal in front for the first time on the night with a goal in the first period of extra-time, only for Reading striker Pavel Pogrebnyak to make it 5-5.
But Walcott restored Arsenal’s lead before Chamakh completed the scoring.
A remarkable night was further added to by the faintly ridiculous moment when Olivier Giroud and Francis Coquelin threw their shirts into the crowd, thinking the match was over, only to have to awkwardly ask for them back once they realised extra‑time was still to come.
