Game of Thrones' Theon Greyjoy visited Arsenal and had the best time ever

English actor Alfie Allen's Theon Greyjoy character might be known for his treacherous ways in HBO's wildly popular "Game of Thrones" series, but in real life he's a staunch Arsenal fan. On Monday, he made a visit to the Emirates Stadium and was welcomed warmly by the London club.

They broke out a version of Theo Walcott's chant for him, and he got a full stadium tour to boot. Allen was clearly excited too, and he went on an Instagram rampage, posting a number of pictures and videos from his trip:

Just like a normal fan, he got a selfie pitchside:

And then he further ensconced himself in Arsenal fans' hearts by posting a pic of two of the Gooners' greatest ever players, Ian Wright and Thierry Henry with the caption "LEGENDS":

Allen got to peek inside the locker room, which he dubbed "the inner sanctum":

And finally, a Theon Greyjoy visit wouldn't be complete without Arsenal's own turncoat-turned-hero, former Tottenham and Arsenal legend, Sol Campbell.

Not a bad day for a die-hard Gooner.
