A late scare against Port Vale was a big reminder to his team that they are not close to being the finished article despite their lofty league position according to Michael Duff.
Holding a 3-0 lead heading into the final ten minutes at the Jonny-Rocks Stadium, Vale hit back through as Will Swan and Alex Hurst's to add some unexpected late drama to proceedings.
Duff's men were able to hold on successfully to three points though and make it four wins in a row in League Two.
He wants his players to take it as a lesson that they can not switch off or let their mentality slip - needing to be on their game for every second of the 90 minutes.
