Cambridge United boss Jez George has said he was unhappy with his side's defending in the 4-3 win at Bath City.
The U's twice trailed the basement side before eventually winning thanks to Tom Shaw's superb finish.
"There was a lot that wasn't right about our defending. We can't hide behind two debatable penalties," George told BBC Radio Cambridgeshire.
"When we watch the DVD a lot of that stuff is going to look like a horror show. We have to be more resilient."
Cambridge are now just one point outside the play-off berths after four wins from their last six matches.
He added: "It's good for the fans who've made the trip, they've seen a seven-goal thriller and some great goals.
"But we've had to show all our quality on the ball tonight because of how soft we were off it.
"To progress we've got to defend better than that both individually and as a collective unit."
