Earlier, Danny Nardiello had put the visitors ahead with a superb strike but it was not enough as Knill's men failed to capitalise on their advantage at the Prostar Stadium, despite the manager's insistence his team were the better side.
"Their centre-half made a run up field, gets a ricochet, but keeps going so a good goal for them but bad for us. Performance-wise, I think we were the better team by far," said Knill.
"We created chances, passed it and moved in around in incredible conditions and our goal was great, just the sort of thing we try to do in training moving the ball quickly down the sides and then a good finish.
"Someone will say we've only won one in five or something stupid like that but they've been tough games and we're unbeaten in 10 with only one defeat away all season."
