"That was very disappointing" he told the Mansfield CHAD after the game.
"We had a good chat in the dressing room afterwards and what was said stays in there - but the lads know that's not good enough.
"You can't give a goal away so soon after the start as it gives them a lift straight from the off.
"We defended very poorly. I have never seen the back four play as badly and we defended poorly overall as a unit.
"We did deserved to get back in it but you can't afford to score a goal and then just think it will come - you have to work hard and keep going.
"We quickly them away a bad second goal and that gave Lincoln a lift again.
"In the second half they were by far the better team. I don't think it was a case of heads dropping but we didn't play particularly well and they were better than us all round the park.
"To be fair I thought Lincoln played very well, particularly their front two.
"But most of their chances came from our own free kick and corners and them breaking away.
"We will now spend the week working hard on what went wrong before we go to Morecambe next weekend which will be a difficult one."
