Stags' boss Steve Evans admits he was disappointed with his side's display in this afternoon's 2-1 defeat to Accrington Stanley.
Stags slipped to their first defeat of the season at the Wham Stadium, despite striker Lee Angol scoring his first competitive goal in Stags' colours after he cancelled out Stanley frontman Kayden Jackson's opener.
Former Stags' striker Billy Kee then snatched all three points for the hosts with a close range finish in second half stoppage time.
And despite admitting his side didn't play well enough to warrant a victory, the gaffer also believes the Stags didn't deserve to lose.
"We didn't play very well, that's the first thing. We thought we were poor today but we certainly didn't deserve to lose the game," the Stags' chief said.
"We've come today and we've not got a lot in the game, but we don't blame the officials. John's team have worked hard and they've nicked two extra points. We have to take it and just move on.
"We thought we were poor today but we certainly didn't deserve to lose the game."
"We learn from it, we go back on the training ground. You learn that if you don't play well, you don't deserve to win games.
"We didn't deserve to win today in terms of the quality of football, but if it was based on possession and patterns of play, we'd have won it."
Stags enjoyed the lion's share of possession in the first half and the former Leeds United boss believes his side should have been ahead at the break.
"We shouldn't have turned one each at half time; we should have turned two or three-one up. We never took advantage of good possession.
"In the second half, there was a spell where they couldn't get out of their half as well and they resorted to long balls up to the two front lads who are quite bright for them.
"They've nicked two points at the end and we wish John and his team well and we'll go back on the training ground and we'll go again."
Stanley's two goals came from set pieces at the Wham Stadium, to which the managr said: "[Their goals were] two set plays, that's disappointing, so we'll have to look at that.
"I think for the first one, Krystian Pearce gets too tight and Zander [Diamond] can't get across. Zander was undecided whether to go or not, the second one, Billy Kee taps it in when Hayden White should mark him.
"We'll learn from it, we'll try and learn from it and we'll go again next week. It's a disappointing day. It's a tough place to come, as always, and we didn't deserve to lose, but you don't get, in this game, often what you deserve."
