Pick up soccer games in Bang Na area

Hi All

Im from South Africa and moved to Bangkok, Im looking to get into some casual soccer games around the Bang Na area.

I know of some games played at the Bangkok Patana School for leagues. If anyone has info of some fun meet up games around the area please let me know.

Hi I see there is an outdoor field near by MegaBangna "The Primary Football Field". But I'm not sure if they have any league.
