Alfreton have not kept a clean sheet in their last six matches
Expert verdict
Alfreton have won just one of their six games since being deducted three points for fielding an ineligible player and their slim play-off hopes could be ended by a home defeat to fourth-placed Grimsby. Staying in promotion contention for so long has been a good effort for part-time Alfreton but the wheels have come off in recent weeks and they may struggle against the Mariners, who have won four of their last five away fixtures.
