"The game should have been put to bed early in the match with us creating countless chances but we struggled to hit the back of the net," Hendon boss Greg Corin told JC Sport.
Praising full-backs Mordy Weiler and Dudi Edreyi, as well as the in-form Seitler, Corin believes the best team won.
He said: "Our misses created some nervy moments but in the end we were deserved winners and it would have been a travesty if we would have dropped points.
"We have some huge league games ahead so getting the three points today was vital if we want to mount a serious challenge for the league title."
Lions boss Sam Marchant was clearly impressed by the victors. He told JC Sport: “Hendon are probably the best football playing side in the league and we knew that going in to the game, and set up a game-plan which was actually extremely effective.
"The first goal of the game came as a result of a bit of luck and a lapse of concentration by our defence, and the second goal came in the final minute when we were pushing high up the pitch for an equaliser.
"The game itself was actually very close and could’ve gone either way, with both teams creating dangerous opportunities in the first half.
"Hendon are a nice team, they play well and edged us on the day but we actually did very well, we played as a compact unit and restricted their fast forwards extremely well.
"As I said, another day this can go our way but today it wasn’t to be. Our focus immediately turns to next week's big Peter Morrison game at home where we feel a victory is due and nothing less will be accepted”
