Uwe Rolser says sticking together is important following Tuesday night’s defeat at Walsall.
Rosler’s side lost 4-2 at The Banks’s Stadium, after Town took the lead through former Saddler’s loanee Jordy Hiwula, with two late first half goals saw Walsall lead at the break.
Town equalised courtesy of Amari’i Bell’s first time finish, but goals from Tyler Roberts and Daniel Agyei gave the home side all three points.
Rosler now knows togetherness is key ahead of their derby match against Blackpool on Saturday.
“It is very important that we stay together,” said Rosler.
“I have seen things arising in recent weeks, but I try to put that behind us. This was the first time I have seen that.
“This is the most challenging time since I have been at the club. I have not seen my team like that; and we talk about our three pillars being right because if one isn’t there, we aren’t in a position to compete.
“Now we need to build for the derby match.”
Town created many chances against the Saddlers, and were unlucky to concede two late goals and come away from the West Midlands pointless.
“We started the game really well,” Rosler added.
“Our shape was good and we created many chances. We should have been up two or three before they scored with their first cross into the box.
“We worked hard in the match and had chances on the break with Ashley Hunter, Jordy Hiwula had another opportunity, and Devante Cole had a chance when he came on.
“With those chances, their third goal killed us. When you give the ball away too easily whilst you’re in possession, you just need to pass it out, but we concede.
“They hit us with the sledgehammer.”
The Cod Army welcome local rivals Blackpool to Highbury on Saturday but will be without key players for the match, and Rosler knows his team need to have the right reaction in the build-up.
“Tomorrow we will sit in a room together. We have to be careful because footballing wise, we will sometimes make mistakes, especially when you have a young and energetic team.”
