Boss Darren Patterson paid tribute to the character of his players for bouncing back from Burton with the win they needed on Saturday.
But he admitted also being "agitated" by the inadequacies in front of goal, where they passed up some great opportunities to find the net.
Overall, Patterson was pleased with the response, as the U's dominated the game and played some good football to boot.
But against limited opposition, they should have eased to victory, rather than having to hang on.
"A win's a win, we're away from home and it's a clean sheet," he said.
"The lads showed a lot of character. There are quite a lot of individuals who have been coming in for quite a lot of stick from our fans and quite a few of them stood up today to be counted, so I'm very pleased.
"We scored one, but if I put my hand on my heart, I'm quite agitated because we should have had three or four.
"You can see why we don't score goals. The amount of times we refused crosses into the box, it was incredible. I think sometimes we think we're Real Madrid and we've got to have 20 passes and then put it in - it's ridiculous."
Matt Green got the winner in the 11th minute - his fifth goal in ten starts for the club.
Patterson paid tribute to Eddie Anaclet, who gave a superb performance, but was less enamoured by Craig McAllister.
The centre forward, when through on goal, bizarrely chose to pass it to midfielder Jamie Hand, when he was in a much worse position.
"When my striker's 18 yards out and he's got a shot on goal, and he passes it to somebody else, I can't believe it," fumed Patterson.
"At the end of the day, we don't score enough goals, and if the centre forward's not going to be selfish enough to have a shot when he's clear on target, I don't know who is."
The manager was delighted with Anaclet, though.
"Eddie was excellent, and everybody in the dressing room was hugging him because people have been saying he's looked low on confidence, but today he has put that aside.
"That's his best game for us for quite some time.
