If he was on 750k then we could get one heck of a foreign marquee for that sort of cash. It might have been that the management hoped that a home town boy done good would increase crowds, but most of the marketing that I saw was around Krishna anyway.
Even attracting Burns back would probably get more bums on seats after how he performed last time he was here than Kosta did.
Ultimately if he doesn't want to be here then it's better to say to the coach here's a heck of a lot of cash that you can spend on your much talked about European contacts.
David Dome said on the radio that they thought about it for four months and waited to make a decision until the new coach was involved, so it seems as though there was the opportunity to force him to stay but the coach was reasonably happy for him to leave. It certainly seems less extreme than the Powell or Tratt reasons for leaving.
What I'd like to see though is the club to hang on to these players until the last moment and try and make some money off selling them overseas, or at the very least trade them with other A-League clubs.
If his partner really was homesick then she's going to have trouble being in a relationship with a footballer or she's really going to hobble his career aspirations.
