Colchester boss Joe Dunne says his side must stay positive after they were thrashed 5-1 by Peterborough in the Capital One Cup.
Lee Tomlin was the two-goal hero as Posh cruised into the second round, while Gabriel Zakuani, Tyrone Barnett and Tommy Rowe were also on target in a landslide victory.
Jabo Ibehre grabbed the U's only goal of the game and Dunne admitted he was a little shocked by the final score.
"Up until their second goal, there wasn't much between the sides and I certainly didn't think it was going to finish 5-1," he said.
"But the third and fourth goals were class and after the third, we went to pot a bit. I felt really disappointed by that, but we have to keep it in perspective, given the stage of the season we're at.
"What I don't want is negative feelings around the place already. We had enough of them last year. I'm positive about the way we're going about things and we have to stay positive.
"There are a lot of positives around our club at the moment. There will be a lot of people saying 'here we go again', but we're two games into the season. They need to stay positive and stay behind the team."
