Fazrul Nawaz netted the only Singapore goal with a 25m volley from a Khairul Nizam knock-on in the 84th minute.
"Denmark is physically and technically better, but our boys gave them a bit too much respect and allowed them to take control of the game”, coach Avramovic said after the match.
"However, we have to remember that this is the first senior international tournament that many of the young players are involved in. So, any team they play now will be at a much higher level than they have ever played before, not to mention against a World Cup bound team like Denmark. The important thing is for the players to learn from playing against big teams like such and raise their game on the international front."
