Shaw was also particularly pleased with how his side dominated the first half against a strong opposition.
“I felt that we did so well first half and I sensed that the boys knew that as well,” he said.
“We were in control of the game and when you get to that stage of the performance sometimes you take your foot off the gas or lose focus, so that was the important thing at half-time, but unfortunately it didn’t heed.”
After the break, the game changed drastically following the dismissal of Derek Agyakwa, who brought down Dylan Stephenson, denying a goalscoring opportunity.
Shaw responded, bringing on defender Josh O’Brien to fill the place left by Agyakwa as Henry Wise made way.
Newcastle took control of the game soon after, with Watford defending intelligently through Andi Janjeva and O’Brien. The latter produced two vital blocks to stop Newcastle from getting their first, throwing his body in the way on the goal-line.
Watford’s best chance of the second half came from McKiernan, hitting the side-netting after a neat run past the defence, but he was unable to score.
The Hornets dug in and produced a fantastic exhibition in defending and game management as they maintained their clean sheet and two-goal lead until the final whistle.
