ASSOC PROF HO PENG KEE, Football Association of Singapore president and Senior Minister of State (Law and Home Affairs)
'It was very difficult for me when I first heard about it.
'I must say he had a heart for the fraternity. He wanted Singapore sport to do well. For that, I respected him, and was a follower of his Sunday column.
'I will miss that, his forthrightness, his point of view. You need an honest person like that.
'I appreciate it, and I think his passion has rubbed off on many people in a positive way. We will all miss him.'
TEO SER LUCK, Parliamentary Secretary (Community Development, Youth and Sports), and an avid triathlete
'I've known him for most of his career and will remember him as someone who was passionate for Singapore sport. Although he was critical at times, he did so because of his love for sport. I will miss him, someone whose voice was much respected.
'He was a true sportsman who battled to the very end.'
NG SER MIANG, former chairman of the Singapore Sports Council and Singapore's only International Olympic Committee Executive Board member
'If there's one regret, it's not having a last meal with him. About two weeks ago, he wanted to borrow a wheelchair and we were supposed to catch up over lunch.
'I prepared sushi, otak and porridge. But then it was cancelled at the last moment and we didn't meet.
'In the 20 over years I've known him, his love for and support for sport has never wavered.
'He will be sorely missed, both at the mahjong table and the golf course.
'I suppose it's time to bid adieu. Goodbye Cheese, till we meet again. Tell the birds on the fairway they're no longer in danger.'
JESSIE PHUA, Singapore Bowling Federation president and Singapore National Olympic Council vice-president
'He was very friendly, and also knew what he wanted and set out to achieve that. He was also a good writer and a serious one.
'I've known him ever since he became a sports writer, which was 20 over years ago. His Sunday columns had a lot of meaning in them; sometimes, they're hard-hitting.
'But, overall, he did it for the good of local sport in the hope it would develop further.'
LOH LIN KOK, Singapore Athletic Association president
'I first knew Cheng Khoon when he was a teacher at St Patrick's and I was an inspector of schools, more than 30 years ago. He was a very dedicated teacher, and very focused on his job, whatever it was.

JOHN KOH, former FAS general secretary and SSC deputy executive director
