I know the previous site was next to the mosque but that's since been fenced up for redevelopment (raises fists!!).
Came across this other place, just across the road.
This one is the other opposite side of Tampines Concourse:

If confused where, then consider that Tampines Concourse is in between the mosque and this field in the photo.
Seen some foreign workers play cricket there over the weekends.
Maybe another potential for East-siders.
Only problem is, no toilets nearby but if rain should be ok to run over to the Concourse to shelter.
