Jonathan D'Laryea (back)
The former Manchester City trainee D'Laryea says he and the rest of the side know they have to improve.
"The lads are gutted with how they played. A lot of us are embarrassed," he said. "When you have been beaten 2-0 after being outplayed by a better team you can accept it more.
"But when you have just been out-fought then there are really no excuses.
"The resolve wasn't there after we went 1-0 down. We should have had the mentality to push on and fight our way back."
D'Laryea was disappointed the Stags conceded another two goals on their travels.
He said: "It's hard to put your finger on why we played so poorly. It just seemed that some of the players, myself included, were not at it and didn't give 100%.
