About 20% of the population in Wales speak the Welsh language. I was curious if any well-known Welsh players were fluent in the language. There's not a lot of info on the subject but I managed to dig up a few clips and players that speak the language.
Aaron Ramsey (Cardiff City, on loan from Arsenal)
John Hartson (Former Arsenal, West Ham, Celtic, and others)
David Vaughan (Blackpool)
Rhys Griffiths (Llanelli - Welsh Premier League)
Nathan Craig (Everton)
Joe Allen (Swansea City)
Other players who are allegedly Welsh speakers (but I couldn't find any video evidence):
Gabriel Heinze, Wayne Hennessey, Owain Tudur Jones, Gabriel Batistuta, Malcolm Allen
If you're an expert on the subject feel free to help out on this one, I'm sure there are a few more Welsh speaking players out there that I missed.
