Speaking in the Monday edition of the Nottingham Evening Post, Shirtliff said"Macclesfield will probably feel they deserved a point, but we've come away from home and scored three goals. So credit to our players who have done very well and deserved the win because they worked hard.
"They went 2-1 up and we've shown very good character to come back. I was pleased with that. I can't remember another game this season when we've scored in the closing minutes.
"It's very important psychologically to win our first game away from home and to get back-to-back wins. It's a terrific achievement and if we can carry on in this form and spirit we can put a run together. We've shown character all season and deserved more points than we've achieved.
"That's eight points from the last four games so that's excellent form by anybody's standards.
"I'm pleased for the players who worked hard and taken on the work ethics I have tried to instil in them."
