The tricky forward was involved in all four goals including being fouled for a penalty for 2-1 and then slotting home the third and fourth goals in the second half.
"It was a great feeling to be back playing and I just wanted to impress, hopefully I did that," Munns told the Spurs website. "I thought I did well for the penalty and then scored the two goals as well.
"I've had substitute appearances here and there but that was my first start in ages and it was certainly in my head to try to get on the scoresheet and do well for the team.
"Most importantly, it was a great team performance and we won the game. There is always the rivalry between the teams and you could see that towards the end when there was a bit of an edge. It was great to get the win."
