Both teams have scored in Grimsby’s last three League Two games
Grimsby have scored first in four of their last five league and cup games
Chesterfield have made a patchy start on their return to the EFL but they could cut loose against a Grimsby defence who have conceded 12 times in their last four games. Over 3.5 goals looks a good bet as the Spireites showed their attacking potential in a 5-0 away win over Crewe last month.
