Chris Powell believes ‘unity and togetherness’ are what’s needed in what he’s called are eight cup finals coming up.
Blues are without a win in 10 games and have fallen closer to the relegation zone as a consequence.
They travel to the ABAX Stadium where they’ve not lost in their last four league visits – three wins and a draw going back to 2009.
After last weekend’s 1-0 defeat to AFC Wimbledon, Powell said: “We need a reaction. It’s the first of eight cup finals because we’re in a position no-one wants to be in.
“But from 12th down we’re all in it. It’s not as I we’re cut adrift.
“For ourselves it’s got harder as the season has gone with confidence, results and losing players but we’ve got to fight through that.
“This period is vital for everyone and we have to be up for it.
“It doesn’t matter who we play, whether it’s a side lower down or a side striving for the top, they’re all going to be difficult game.”
He added: “You have to back them and I understand there will always be frustrations because everyone wants their team to do well.
“We have to have unity and togetherness about us in these next eight games.
“The next one is Peterborough and we have to show spirit and fight to get ourselves out of this position, and that’s what we’ll do.”
Peterborough themselves have lost their last three, but Powell won’t be taking Darren Ferguson’s side lightly.
“The last three games haven’t gone their way but they do have talent, they do have match-winners and we need to stand up to that and find our own match-winners because we need wins.”
