With Singapore striker Indra Sahdan Daud currently on trial with Real Salt Lake, I thought it'd be interesting to see if there was any other talent in the Southeast Asian region that could make their way to MLS. I'll admit I know next to nothing about these players or the leagues they play in. I spent a few minutes looking through wikipedia and these are some of the players with similar credentials to Indra Sahdan Daud.
Phan Thanh Bình
Le Cong Vinh
Mohamed Noh Alam Shah
Indra Sahdan Daud
Indra Putra Mahayuddin
If I had to guess, these players likely wouldn't make the cut in MLS, but without really knowing anything about them or the leagues they play in, it is just that, a guess. I personally hope that Indra Sahdan Daud and other talent from lesser known soccer regions make it to MLS in the future. It can only help the league grow worldwide. If any Southeast Asian soccer fans have anything to add, please feel free.
There are also some interesting Real Salt Lake viewpoints about Indra here and here.
