got info from Roy (not directly) just prior to Christmas that he was happy - no issues with the club, things may have changed but I don't think any striker is ever completely happy playing defensive football that we have seen in the last two games but he is a good pro so will do what is required and hope we play some more attacking football once we have all our reinforcements on board.
Could just be bloody hot and he's done a lot of running?
It's really not that hot in Melbourne at the moment - only low 20s. Plus, he is Fijian; they're known to be able to handle the heat :)
He's also been walking around the pitch and his general body language has been downbeat; which is very unlike him unless he is carrying an injury still.
