The president of FAS, Mr Zainudin Nordin, in his address said: "Rain or shine, the fans have been unselfish in their support for the Lions and FAS. We will go all out to give our best and we hope for the fans continued support. The MSL also offers our young Lions to show what they have to offer and that would be the best showcase for our ongoing youth development programmes.
"As for the corporate support, we are especially grateful to Starhub, Nike and all our sponsors, for their generous support and the FAS appreciate the support and it looks forward to collaborating with them over a long-term period."
