We're used to seeing fans arguing on Arsenal Fan TV about Arsene Wenger, or calling Adrian Durham on talkSPORT to rant about the Gunners, but now the AFC debate has sparked a row on social media between Gary Neville and Henry Winter.
Times journalist Winter penned a newspaper column criticising Neville for his dismissal of an Arsenal fan as "an idiot", after the Gooner was seen holding up a banner calling for Wenger to leave his job as manager.
Former Manchester United defender and Valencia manager Neville is now a pundit on Sky Sports, where he aired his view after seeing the supporter's protest, which followed the North London club's 3-1 defeat at Chelsea last weekend.
