"It's up to the manager really and what he offers," Westcarr told the Express and Star.
"At the minute, I am here training but I have got to sit down with the manager. I would like to stay. Hopefully, we can sort things out sooner rather than later - you can't stick around for too long.
"I just need to wait for the manager so we can sit down and try to sort something out this week, or that's it probably."
