When it comes to the reason for the turnaround in fortunes, for Williamson it's simple.
"It's a reaction," he told nufc.co.uk.
"The supporters were obviously upset by it and, I can't speak for anyone else, but for me it was one of the worst defeats of my career.
"I can't stand losing those games that mean so much. I hate it.
"We have two clean sheets and two wins now against two difficult teams, so everyone is very happy. We knew we were capable of it"
