Knill said: "It was a big win, especially being 1-0 down and losing our centre-half Ben Futcher to injury.
"We were excellent second half and we were more than value for the win.
"I'm disappointed for Futch because he's been outstanding, but Sodje gets his chance now and that's football.
"But I have to say that was a fantastic performance. I thought it was pretty entertaining stuff the way we played second half and we could have won it comfortably."
