I will never get my head around the concept of picking a team to support. I firmly believe the team picks you. To support a football team, means that you would support them if it was relegated all the out of the leagues. People who pick a team from a list only pick that team because they are after glory, when that is not achieved they fuck off, or constantly bitch about not spending enough money, wanting mangers sacked, owners run out of town, players should be sold, why aren't we more like *insert name here*.
If you are looking to support a team for life than look for a team the the way you found your wife of loved one. Have some fun, play the field and one day a bolt from nowhere will hit you. You don't know why, she might not be the best looking bird, she has a stupid laugh, you just know she's the one.
