Oxford boss Chris Wilder says his team need to work hard to put things right, following Saturday's latest defeat.
The U's have now gone five games without a victory and have three matches remaining of their season.
But under-fire Wilder is determined to make sure their season ends on a high.
"I have no problem with the enthusiasm and commitment, I just think it's a tough period," Wilder told BBC Radio Oxford. "We need to go again for the next game."
Oxford's three remaining matches are against Dagenham & Redbridge, Rochdale and Accrington, and Wilder has urged his struggling side to bounce back.
"We try and prepare and set the team up with the numbers we've got because we've got a few down," Wilder said.
"When players are playing with no belief or confidence it does really make it hard.
"We've got to regain that [confidence] by keeping going, sticking your chest out and working as hard as possible.
"Hopefully someone does something that gets us up and running again."
