10 things...

Swansea
1 They are west Welsh and know they are - a rugby club to boot, since circa 1900.
2 Southern League accepted Swansea Town because they had a pitch of sorts. It was an ex-cabbage patch, or a vetch field for producing cattle fodder.
3 After WW1 they transferred to Football League, who didn't mind having representatives from another country in div3. They're Welsh and know...
4 Between the world wars they Swanned about in div2 and pretended to really like being better than a small town in Cardiff.
5 After WW2, Town hit the skids and ended up in div4. Rivals Cardiff meanwhile had reached the top flite, to rub it in Welsh south coast style.
6 Not long after the sixties Town became City, where Vetch Field was hosting div3 then div2 clubs. They were singing by the seaside on North Bank again.
7 In the eighties City got into div1 and the club began spending in earnest. Then spent more, again and again. They then predictably went bust in 1985. Oh, also relegated back to div4, again.
8 In the nineties Swansea actually won the 'English' Autoglass Trophy but no one flipping cares outside er, Abertawe. It's because European Cup competitions were now inviolate to Welsh silverware winners - so there.
9 Mascot Cyril the Swan was nicked for bringing the game into disrepute in 1999. The club had been doing that for years and getting away with it.
10 The City Council demolished an athletics stadium at the old Morfa site to build a new arena for the 21st century. Btw this ultra modern venue does not have a running track around the pitch. Nor does reworked Wembley 2 apparently - oh, well...
