The Everton 2010 game must've officially been the coldest match I attended but I recall the Salzburg game the same season as feeling the cold more. Either way, I was well wrapped up at both and because I was near the back of the first tier I wasn't as open to the elements as other fans. As such, the coldest I've ever felt was stood on the open end at Stamford Bridge for a 0-0 bore draw on a Monday night in November 1993. I think it was about -3 or -4 that night but it felt a damn sight colder and I think it was the smallest away following I've ever witnessed. There weren't many Chelsea fans there either as the attendance was just over 10,000 and it was that shit and cold that I don't recall a single chant from our end behind the goal during the whole match, or any from the Shed for that matter, though there were a few "Swales Out" chants from the 50 or so blues who were in the seats high up in the third tier.
