Mention of Mr Caramella`s upbringing in Cardiff was given when he was appointed as a director in late 2017 and it was said that he had a role of raising Cardiff City Football Club`s profile abroad (assumedly in Malaysia where he is based). According to everyone I know who has visited Malaysia and those I know who have worked there for many years, CCFC has no profile there so seems unlikely that he has been carrying out that task for 6.5 years.
Chin has been a long time employee at Berjaya Group (recently promoted to their board) and, as you say, is a lawyer. What his contribution to CCFC is remains uncertain as the club`s legal advice is provided by Capital Law in the UK.
Danni Rai is also a solicitor with his own small practice in Malaysia and was previously employed (not as a solicitor) by Berjaya. His importance to Vincent Tan is more likely to be the fact that his father was a leading politician in Malaysia - until recently leader of a political party and President of the upper house of the Malaysian Parliament. There is no suggestion that he has ever made a positive role in CCFC itself.
Although it is mentioned in the minutes of the recent FAB meeting with the club that the above three attend all board meetings (I personally find that hard to believe) , it is difficult to see what possible football or football business knowledge they would contribute to such meetings.
Once in place an Independent Regulator will require the club to submit a Personnel Statement properly setting out what the title and role of every director of the club is. This will be a statutory requirement, without which the club will not be given a licence to operate as a professional football club in any of the top five divisions in the game.
