For me personally the four I'm thinking of at the moment are Petrie, Kevin Thomson, Dick and Ian Murray.
Petrie is the obvious choice, just as he was a year ago before we got Peter Grant and then Yogi in November. Kevin Thomson wants a new challenge, has been interviewed for Raith, I think he'd be a good fit. Ian Murray has done very well at Airdrie, would tick the boxes similar to Kevin Thomson. Rumour has it Dick applied both times the job was last available and wasn't offered an interview which is bonkers. Like Petrie, the Pars are his club and I'm sure given our current position would see it as a good challenge. Can't see him taking Arbroath further than he has this season.
