Aside from your own idiocy, the biggest threat facing undercover fans are the supporters immediately around you. You're only ever one iffy reaction to an Emmanuel Adebayor mis-control from raising suspicion and blowing your cover. The threat posed by those supporters immediately around you is much more real should they try and engage. As all football attendees know, the nation’s stadia are littered with odd men keen to discuss their in-depth feelings towards certain players. They attend the match alone and have done for decades. A man sat just in front of me was very keen to debate Carlton Cole’s application levels. Every few minutes he’d swivel and launch into a furious anti-Carlton tirade. Now, this was easy for me to convincingly join in with. Football fans worldwide can find common ground with someone who believes Carlton Cole to be quite rubbish. It became trickier to nod along when he started picking on Tottenham debutant Eric Dier.
