Knill's men head into this weekend's home match against Hereford in third spot.
"There are 21 games left and we're the ones that are in control," said Knill.
"If we do really well in those 21 games, then it will be a great season.
"That's the aim for us, we don't worry about other teams and what they do and how they go about it. This really is about us and what we do."
