"I thought the fans were superb today," Munro told ITV1. "They never let us down and they played a part today. They pushed us through.
"They realised we were very tired towards the end having no substitutes, but when they're pushing they suck goals in, and I think they sucked Craig’s goal in today."
Munro conceded, however, that United had dominated much of the second half without creating many chances before Cosgrove finished them off in the 82nd minute.
"We've got to give Nettleham United credit," he said.
"They controlled large parts of the game but the most important thing was the result and we got there in the end.
"you've got to give the team credit for all the effort and commitment for the way we played today."
Munro’s manager Al Taylor was full of praise for the striker who has endured a frustrating season.”
“Billy was absolutely superb today.” Said Taylor
“His contribution to two of the goals in the first half was superb and his hold up play was excellent but more than that he ran his socks off for us.”
“We’ve said all along that it is about the squad this season and Billy’s attitude has been absolutely spot on,”
