Since this is the more appropriate thread for it I'd absolutely try to go to a game in Southampton if I get there. I've been to EPL and Championship games in the London and a little out of London areas and have always had a great time. Craven Cottage is my favorite place I've seen a game so far. It's harder to see numerous games over there with the scheduling since it's not like the Devils where they play like 4x in a week and with how hard it is to get tickets for some games.
I'm mainly jealous of how close everything is for traveling fans. You guys can go to almost every home game since every city is like 5 hours away or less. I have Red Bulls season tickets in the MLS and the only teams in the entire league I can see under 5 hours away is 4 teams, NYCFC, Philadelphia, D.C. and New England. Everything else is either a drive that requires a hotel stay for the night or a flight.
I'd go to almost every single game of whatever my favorite team was if I lived over there with everything that close.
It is brilliant.
Football is so deeply engrained into the working man's culture here, it's virtually treated as a religion. Or at least it used to be, I won't get into it here but the short version is that money destroyed the premier league.
Just my humble opinion.
The Championship is an absolutely brilliant football league and is much closer to what football of old used to be. But even that league has become a house of cards that could crumble at any moment.
But yes, the ability to hop on a train and follow your club all around the country is certainly an aspect of European life that is totally underappreciated.
Edit: I'll add that if you wanted to experience South Coast football, you'd be well placed even if you stay in London. Southampton, Portsmouth, Brighton and Bournemouth are all located within two hours train ride of the capital and very easily drivable if you were to rent a nice little diesel hatchback car. All above are connected by motorways to London (well except Bournemouth, but it's well connected to Southampton by a "dual carriageway" two laned highway).
Zipping around by car is extremely easy here and well worth the drive.
