Manager Darren Ferguson hailed a masterclass from transfer-listed striker George Boyd in the 3-1 home win over Huddersfield which lifted Peterborough off the foot of the npower Championship.
Boyd struck twice, including a stunning long-range effort, and also laid on Peterborough's third goal as they finally collected their first home points at the sixth attempt.
Ferguson said: "George's first goal was very good, but his second was nothing short of world class. He has had a little look, spotted their keeper off his line and executed his shot brilliantly. If Lionel Messi had done that you would be seeing it over and over again.
"Those two goals gave us a great start and we built on it by producing an excellent all-round performance.
"The players got the tactics spot-on and caused Huddersfield countless problems."
Terriers chief Grayson was left to regret naming an unchanged team following a fine weekend win over Wolves.
"There is no doubt Peterborough deserve their victory," said Grayson. "They have been struggling of late and we arrived on a high, but it goes to show what can happen in this league.
"We didn't play well collectively. We over-elaborated and made poor decisions on the ball and we were too slow on and off it.
"We received plenty of hype after the weekend and I wanted to give those players the chance to get another win, but maybe I should have made changes. We all know hindsight is a wonderful thing but we need to make ourselves harder to beat than that.
"When we got back to 3-1 I thought we could get onto the front foot but it didn't happen."
