For reasons I can't really understand, Bet365 have Gillingham's joint 2nd highest scorer this season, Max Ehmer, at 16/1 anytime scorer or 40/1 first or last scorer. He's a central defender, but always a threat from set pieces, and has got 5 in 23 games this season. Only forward Jay Emmanuel Thomas has scored more than him, and he's level with our other main striker, Cody McDonald, yet according to the odds, Bet365 think he's the least likely to score.
According to Oddschecker the price is around 7/1 at quite a few other bookies, that's probably a touch too short, but 16/1 is huge.
