Exeter boss Paul Tisdale admitted his team put in a poor display as they suffered a 1-0 defeat at home to Wycombe.
Max Kretzschmar scored the only goal of the game with a 35-yard rocket which flew over the head of Grecians goalkeeper Christy Pym and despite plenty of the ball the home side failed to make their possession count.
"It was very disappointing," Tisdale said. "I'm disappointed with the result and the way our game was pieced together.
"The one thing you don't want to do against Wycombe is concede a goal because they set out to defend. They go a goal up and their focus is clarified and we found ourselves in that situation, which was the last thing we needed.
"We couldn't piece it together and we looked incredibly nervous and anxious, we didn't make the correct decision. There was a hell of a lot of effort, but when you are disconnected the effort goes into the mud and that's how it felt here.
"The players were exhausted at the end but it was misdirected energy. We did some good stuff but we failed to show the appropriate levels of composure around the box when we got near there. It was a very, very disappointing night."
