Port Vale goalkeeper Stuart Tomlinson revealed he is desperate for the team to recapture the defensive form the side had under former boss Micky Adams.
The Valiants recorded an impressive 12 shut-outs in League Two under Adams and boasted one of the meanest defences in the division.
However, after Adams left for Sheffield United in December, Vale have struggled to recapture their defensive form, and have failed to keep a clean sheet in their last 10 games.
Tomlinson told the club's official website: "I think we showed good character at the start of the season and we were flying.
"But there is no point going on about how good we might have been, or how good we were then, we have got nine more games left to show how good we can be.
"You get judged on how many clean sheets you keep and at the moment that record isn't good enough.
"It is disappointing, but not just for myself; I am sure if you asked Chris Martin and any of the back four, they would say exactly the same thing."
