Corrected entry: Before the first match we see people in the Abbey wearing West Ham jerseys, but when they are walking to the game none of them do.
Corrected entry: When Matt character arrives in London, his sister tells him the debris in the streets is from the previous evening's football match. Matt then goes with Pete to another match that evening. English football teams never play on consecutive nights, and do everything they can to avoid playing twice in three nights.
Corrected entry: When Pete is explaining to Steve how he lost his wallet and keys, his cab pulls up outside and honks. When he leaves with Matt, they walk to the bar, with no mention of the cab.
