Leigh Griffiths has questioned his future in professional football after being a free agent for five months and no managers picking up the phone.
The former Celtic hitman has been training with Livingston to keep up his fitness in a bid to find a new club. Lions boss David Martindale has offered the hitman facilities but has said no deal is on the table to return to the pitch full time.
Following his exit from Parkhead, Griffiths had spells at Dundee and Falkirk before going out to Australia to turn out for minnows Mandurah City FC in the hope of attracting interest from clubs in the A-League by putting himself in the shop window. But he has returned from Down Under and is still training at the Tony Macaroni Arena.

The lack of calls has Griffiths questioning whether he has a future in the game as time continues to pass. He told BBC Sport Scotland: "The longer it goes on I think, 'Is football for me anymore? I've been without a club for five months now and, although Davie [Martindale] has said I can come in and train with them, he has said there is no deal on the table.
"I'm still not seeing managers pick up the phone, which means do they want me at their club or is it time to call it a day? That is something I'm still considering at the minute. As a free agent you've not got a budget, you've not got a price-tag on your head, everything is still negotiable.
"I think that was probably the lowest point for me [Celtic dismissal]. I hold my hands up, I regret what I did. It went to the right people behind the scenes, from Celtic, the authorities, the law, and I have proved that there was no wrong doing. But for me it is still a massive mistake and a massive regret."
He added: "Even yesterday, I got abuse when I was training at Livingston. People just standing at the top of the hill wanting to stand and abuse me.
"I can't do anything. I can't go out to the shops. That's the narrative, that's the stigma you have when you're playing with one side of the Old Firm.
"Don't get me wrong, there are plus sides as well. Celtic fans still come up to me and say they miss me, which is always nice to hear. There's always that flip of the coin."
