Gillingham manager Mark Bonner felt his side had enough moments on Tuesday but was frustrated that they couldn’t make it count.
The Gills had more of the ball and more chances but it was a smash-and-grab effort from the visitors who went away with three points after converting their only on-target effort of the night.
Bonner said: “I thought we were fairly dominant but like we've done to other teams, (it was a) perfect away performance. “I think we've given them a goal that is absolutely preventable in two or three moments for us. “I said to the lads that our defensive record has been amazing, so you can't hammer them for that, but for the goal itself we get dodged twice too easily and they run through the middle of the pitch way too easily. “We're way too narrow as a back four and we don't deal with the moment that's scored and (goalscorer Kieran) Green caused a lot of problems in the first half.
