Knill feels they should have done better, and said: "I am very disappointed. We conceded an early goal and gave ourselves a mountain to climb.
"It was a lot better in the second half but it shouldn't take me to do what I did at half-time to get people going and the end result was a 3-2 defeat.
"If players want to better their careers they have got to push themselves more and be aggressive. That's all I am asking."
