Gareth Ainsworth says his side looked nervous in their defeat to Newport County on Saturday.
Wanderers shaded the first half with Nick Arnold seeing an effort cleared off the line, before Steven Craig’s header was tipped over by keeper Ian McLoughlin.
However, the hosts stepped up a gear after the break and Blues were unable to respond, eventually going down 2-0 thanks to goals from Christian Jolley and Chris Zebroski.
“I don’t think anyone had much of the ball, it was a terrible game to watch and I think the ball was in the air more than it was on the ground,” he said.
“I’m really disappointed with that; I wanted us to get our feet on the ball and start to play a little bit.
“In the first half I thought we had the majority of chances – their keeper made a couple of great saves and there was one off the line – but in the second half I couldn’t recognise the team. They just seemed to fall to pieces.
“We looked nervous, we looked like we didn’t know each other; totally foreign to the team that beat Dagenham.
“I’m flabbergasted at the performance in the second half. It just wasn’t good enough and we’ve given ourselves a real battle now with the game against Northampton on Friday.
“It’s been a real bad day and I’m going to have to look real seriously at the video and just get these players back up. Friday is what we’ve got to focus on now; we’ve got to put that to bed quickly.”
