Bradford boss Phil Parkinson was frustrated after seeing his team surrender a half-time advantage in the 3-1 defeat to Cheltenham.
Nahki Wells put Bradford ahead in the eighth minute with a fine low finish and Ricky Ravenhill struck the post, but but a brace from Jimmy Spencer followed by a third from Ben Burgess sealed Cheltenham's third straight home win and guaranteed them a play-off spot.
"It was a game of two halves because in the first half we were very good and we could have scored more," Parkinson said.
"We hit the post, had numerous other chances to extend our lead. Cheltenham were always going to come out fighting in the second half and up their game.
"We stopped winning headers at the back, stopped squeezing up as a back four and we weren't compact as a team, allowing them far too much space all over the pitch.
"It's a shame because in the first half we were so good. We came up short in the second period and didn't compete as we should've done."
