Clark said a 3-0 away defeat at Plymouth last November was "a watershed" for the new managerial team at Carrow Road.
Clarky: 'The Game That Changed Our Future'!
Since that 3-0 defeat at Home Park, the Canaries have lost just once more - and that to a last-minute strike in the 2-1 defeat at Stoke City on the first Saturday in December.
When Norwich fans were asking serious questions about Clark and Roeder, the pair suffered that defeat and knew things HAD to change.
37-year-old Clark: "It's going really well. We've had a great response from the players - they've have really bought into what Glenn and I are trying to do.
"Plymouth away was the watershed game for us - it showed that we actually needed to make a lot more changes than we thought.
"I think the players that we brought in from the Premiership raised the standard in training every day and if you do that, then that then raises the standard on match-days.
"We haven't done anything yet; haven't achieved anything - all we've done is given ourselves a good base from which to work from.
"All we're looking to do is just catch the next team ahead of us. It's just a case of taking it one game at a time.
"We've just got to go there, apply ourselves, try hard and see what happens from there."
