Oh if I must
Saaawwwkkka (official new name of the FBIFA)
Manchester United. I think we can all guess why. You don't be a city fan around where I grew up - even less where I'm living now (which, alas, because I'm skint, is in Old Trafford...). Remember my first game was a reserve game at Old Trafford in 90/91 season - must've been a kids go free thing because my dad and 2 of his mates decided to take their sons along to a couple of games. We got beat by Everton 3-2, Mark Robbins getting both our goals. I was happy that Bryan Robson was playing on the way back from another injury, dad was just amazed by this Welsh kid on the wing who he predicted would be a utd legend (then spent the next 20 seasons calling him a bag of ****).
Second club is the mighty Trafford FC, just relegated from the Unibond Premier (and to think we were tipped to follow FC Utd to the Conference North this year), screwed over because all the decent players have been enticed by the upstarts at FC and Salford. Spent many a fine afternoon as a teenager playing for their junior team
Have a soft spot for Everton, as it was my Grandads club when he first came to England, for the same reason as I still like them - They're not Liverpool. Keep an eye out for Morecambe results as most of my immediate family live there and my step-dads a passionate fan (I've been to the Globe more than OT in recent years), and Altrincham, as I went to school round there and played for their juniors a few times too. Like most of the forum, I also suffer watching out for Tranmere results too....
Foreign teams
Sound a right glory hunter here, but Real Madrid and AC Milan for me. Milan is a bit glory hunter-ish, as the 89-91 era team was amazing (I was 6 in 89, let me off), stuck with them since, and the kit is teh ***.. Went there for the CL semi in 07 when they beat us 3-0, was a great day and the city is full of fantastic folk, even the Milan fans were a joy. Hated Juve due to our battles against them in the late 90s in Europe, evil team IMO.
Real because when I got to secondary school in 94, Barcelona were the top team, and quite happy to embarrass us in the European Cup (plus I didn't like them because they had the gall to face us in the CWC in 91 - I still remember Clayton Blackmore saving the day). One of my friends family was from Madrid, and he convinced me to support Real. Again stuck with them.
Don't have a German team, Dortmund can do one after 97...
Also, Celtic, because it's ingrained... (soft spot for Aberdeen too, even if the city is one of the dourest to visit)
Other sports (they exist???)
Cricket - Lancashire.... Might be the only thing GIMH and I will ever agree on sporting wise. Actually the only thing Manchester and Merseyside can ever agree on.
Rugby Union - Sale - About the only decent rugby team for around 200 miles (and that includes the League teams - suck it hataz...). Grew up playing union over league (public school FTW) Also free tickets when at school helped
Rubgy League - If I must watch it then Salford, though gone off them since they stuck that huge stadium next door and ****ed up the motorway for getting home from work. Says it all about Salford when they build the stadium at the most remote part of the places boundaries so they can get away from the locals but still claim to be in Salford. They'd rather be next to the sewage works than a Salfordian (smells better TBH)
NFL - Detroit Lions - When Channel 5 (remember that, its still going) launched in the mid 90's, it'd show games late at night (just after your Friday night 70's British smut), Barry Sanders was amazing, so I became a fan of the least successful franchise in NFL. No glory hunting there.
F1 - If you can support a team in it - then Williams, grew up on Mansell and Senna in the early 90's, and then Hill being F1s version of Hugh Grant (wonderfully British, completely inept and out of his depth yet still scores). Went rubbish sure, but always some interesting driving selections rather than just rehashing the old names off the grid each year. Now making Massa look like a racing driver again.
Tennis - Philadelphia Freedom, because Elton wrote a song about them.
