Southampton for English football. I really like their kit, and always had a massive surplus of paul jones stickers when I was a kid. Woking maybe too. When I played for haslemere youth everyone was obsessed with being scouted by woking.
Atletico in Spain. There probably isn't a more likeable club on the planet. Great supporters, awesome stadium and have had some incredible players.. Plus I really buy into the whole corrupt owner thing. Great kit too.
2nd teams are awesome.
