Puncheon was the standout player for Southampton and Adkins felt he should have had two goals today, having seen a first-half header chalked off.
"It was a great goal, I am delighted with it," Adkins said of the goal that did stand.
"Jason could have had a few more. He had a few opportunities and a perfectly good goal disallowed as well.
"But the goal is off the training ground and we have a midfield player dropping out in between the defender and the full-back.
"We get somebody in the pocket, our full-back playing up high and wide player coming inside. Good quick play and an excellent goal."
