arsenal, ajax, barca, brazil, greece, parma, marseille, nigeria, jamaica, italy, southampton, west ham
most of which are because they were CHEAP and have novelty. arsenal ive supported since i was 5 and im 1/4 italian....and southampton because i got one FREE at uni
I have Feyenoord home and away shirts as my ex-wife was from Rotterdam so I sort of supported them, and a grey Barcelona away one. Couldn't bring myself to buy the home one, a bit adjacent to Palace colours.
OK, if we are going as far as listing shirts, my offering is:
Brighton (loads), Hearts, UC Mexico, Vasco da Gama, Allianza Lima, England and Ireland...might have a couple more lurking around in the attic, have definitely had a few that ended up in the bin because they fell apart.
