Yep, their ground is in England and the registered office is in England. Not very Welsh.
And Andy beat me to it on Llanelli.
Perhaps I should ask chislenko on the mother ship about squad members, he's knowledgeable.
Im sorry but i dont pretend to know much about the welsh premier league and never have…….it was formed long after i started watching football. Although i did play for a club that was once in the welsh premier league, but only in a pre-season friendly and not in the premier itself.
You see i was born in the mid 70s when the only football shown on tv was the english first division. Wales didnt have a football league to talk of then, only local non professional club leagues, which i did play in myself until late 2005, when i broke my leg and never recovered to play again.
Hopefully chislenko will be able to give you more details of the league, were as i cant im afraid.
But as for TNS they were formally Llansantfraidd town, until they merged with oswestry in the english league, but played out of the recreation ground in wales, until the owner threw his toys out the pram and moved that to Park Hall, oswestry. Bit like the owner of wimbledon did back in the day after they got relegated from the premier league…..although still based in england, they werent anywhere near wimbledon and then they renamed themselves.
