Michael Duff has been talking to the media ahead of this weekend's 'tough' League Two encounter with Lincoln City at the Jonny-Rocks Stadium.
"It's as hard as it gets at the minute. Lincoln are top of the league and Danny Cowley has done a good job," he said.
"He has brought some good players in and they have started well. It's at tough one, we know that.
"I think everyone knows you have to stand up against Lincoln and if you are not prepared to fight, they will run over the top of you.
"That's one thing the players will be made aware of, that they need to stand up physically and mentally and then have the confidence to get on the ball and play as well.
"It's the early stages and it's not going to be a quick fix. The weeks that we've had in between games have been important and the players have taken things on board."
