Do a deal with Bosnich, in that Lawrie will give him the opportunity to play in the Pre-Season Cup games for $0's, that's right, $0's! If he proves worthy, a further contract could be warranted.
Why would Boz play for $0's?
No one's knocking on his door in England, even lower division teams. What Boz gets in return is to show his wares and see if he's still got what it takes to play high level Football. The Mariners will provide a good stable team environment, the return to Aus also will allow him to see his family regurlary who will also provide him with the 'get back to reality' grounding that he requires.
I believe this would be a no lose situation for Lawrie, as if Boz doesn't work out, it's only the Pre-Season Cup.
Alternate Trotty & Redmayne as substitute keepers in these games or as mentioned previously loan them out to either Lightning or any one of the NSW Premier League teams and make sure they are watched at 'every single game!' by JC for a full and frank performance evaluation, if JC's not watching these games then you'd never really know & JC's not working for his $'s.
I watched Trotty play quite regulary last year for Lightning, travelling to some of the Sydney games and don't ever remember seeing JC there to evaluate Trotty's performances. Lawrie would ring Johnny Mc after games checking on Matty Simon, Chicken & Boogs etc, but that was it.
If Boz can't come up with the good's playing for us in the Pre-Season, well then it's fair to say his dreams of a future in Football will be along the lines of playing with Jamie McMaster at Umina.
