Hibernian manager Colin Calderwood bemoaned his side's defending in the 2-1 home defeat by St Johnstone.
The visitors netted in stoppage-time to snatch victory after coming from behind at Easter Road.
"Simpler play would have got us the point and better defending of a corner would have helped too," Calderwood told BBC Scotland.
"In the end, you would want to take a point and not lose a goal in the manner we did."
Akpo Sodje opened the scoring for Hibs before Liam Craig headed in a Danny Grainger corner after 73 minutes to level.
Craig turned provider in added time when he dragged back for Kevin Moon to fire in a late winner and hand St Johnstone all three points.
"It was very well contested, but we lacked the power to see the game out and get a draw," said Calderwood.
"With 15 minutes to go, we lost a man in the box and it caused them to get back into the game.
"We pushed after that, but we looked second to them in the final spell of the game.
"The goal they got lifted them and it didn't lift us."
