FAS President Zainudin Nordin, who has been in the news lately following a MediaCorp interview two weeks ago, made another televised appearance, this time on ChannelNewsAsia, where he spoke of Sundram's exit and reiterated that the coach was keen on pursuing a new challenge.
However when pressed on whether there were other deciding factors behind Sundram's exit, besides money and the pursuit of a new challenge, Zainudin revealed that the restrictions he had faced in squad selection had played a part as well.
