Coventry City defender Jordan Willis has branded the Sky Blues' second-half performance "embarrassing" as City conceded three goals in the last ten minutes at Priestfield.
Willis was recalled to the side after injury to Matthew Pennington to make his 26th appearance of the season.
But the defender could not help the Sky Blues record back-to-back away victories and believes City gave the ball away too regularly in the second-half, which resulted in the 3-1 defeat.
"With ten minutes to go we didn't expect that result," the 20-year old said.
"We stopped doing the things that we were doing earlier in the game and it resulted in us losing three sloppy goals.
"I think they really came down on us and pressed us higher up the pitch late on. We gave possession away very easily and that's what resulted in the goals.
"They got the equaliser but everyone's heads are still in it, we were confident of getting another goal ourselves.
"But it's embarrassing being 1-0 up with the way we were playing in the first half then conceded three goals, it simply should not happen. We are all hurting."
The game swung on a controversial penalty decision when Ryan Haynes challenged Jermaine McGlashan in the box and referee pointed to the spot when it looked like Haynes got the ball.
Willis admitted he hasn't seen the incident back but revealed his initial thoughts were it wasn't a penalty.
The defender added: "Everyone has to take repsonsibility, we're a team it's not just one person.
"My initial thoughts were that it wasn't a penalty and Ryan had made a good challenge.
"Ryan said after the game that he 100% got the ball. But the referee gave it and we can't change that, I haven't seen it again so I can't say for definite. But if it is a wrong decision it does kill you at that stage.
"We should have carried on the things we were doing in the first-half though, if we had done that we could have got a better result here."
