Account -@CardiffCityFC If ever the marketing power of the Premier League was in doubt, the fact that the 3 promoted clubs are adrift in terms of Twitter followers is a good indicator. In that sense, Cardiff City are ahead of the posse. It's their first season in England's top flight since 1962, and the Welsh club have been busy rebranding - their Malaysian owners changing the colour of their shirts from blue to red, and changing the club crest as well They still lag behind fellow Welsh team Swansea and the rest of the Premier League, but there's promising signs for the Welsh side on the Twitter front at least!
