Jacob Burns signed for Wisla Krakow in Poland after us, hoping to play in the Champions League. He had a brief stint in some Romanian club too, before going back to Australia for a few seasons. If I remember correctly, he announced his retirement from football last summer. No idea about Anderson da Silva.
Think Jacob Burns ended up playing in the same team (in Australia) as Jeronimo (remember him?). Think it might have been Adelaide and they were both very important players for them. Mind you Heskey was good in Australia...
When Anderson came over for that trial a year or two ago he came from Uruguay. Apparently he wanted to resign for us so much as well he paid for his plane tickets and everything to get here for the trial.
The problem is Wikipedia rarely gets accurately updated for low profile players so it's hard to know for sure where they're playing. Dennis Souza has spent the last couple of years playing for OFI Crete & Diego Leon has spent time at Las Palmas in Gran Canaria & then the last 4 years in the Cypriot league. Pretty nice places to play your football. Emil Halfreddson has come up the leagues with Verona in Italy at gets regular games for Iceland including when they bet Holland a couple of months back so they don't all do **** after leaving us
