[LNB][LNB]Kettering Town player-manager Lee Harper tells BBC Radio Northampton:[LNB] [LNB][LNB] "It's been an extremely frustrating day for everybody. We had our chances in the first half, we could have gone in 2-0 up at half time. [LNB]"At home, you've got to be in the opponents' faces from the off. We didn't start either half particularly well. [LNB]"I'm new into the job, and have had a pretty difficult week. But I thought we were unfortunate today, and we've got to pick ourselves up for Hayes and Yeading on Tuesday." [LNB]Harriers defender Duane Courtney told BBC Hereford & Worcester:[LNB] [LNB][LNB] "To win 2-0 and grab three points was excellent. I think in our heads we know we can do anything this season. [LNB]"It's just getting that level of consistency and I think we're finding that now, we're improving in training, we're seeing it in games. Everyone's buzzing around us and the lads are enjoying it. [LNB]"I score so many in training it's unbelievable. There was one thing I was going to do in my head and that was to shoot and I got my first goal for the Harriers so I'm delighted."
