Victory secured their place as they get ready for a quarter-final match on Wednesday, writes Tom Feaheny.
“I knew we had done well in that first period but we need to stretch the game more, use the width of the pitch and be more positive in our play particularly in the opposition’s half,” Quinton told East Anglian Daily Times.
“Once we scored I knew then that with confidence and keeping the pressure on we could go on to score more. I’m also pleased we kept another clean sheet."
Quinton says that the goal that was set out at the start of the season, has now been achieved.
"Despite one or two setbacks en route all the players have worked hard and we’ve achieved our goal of getting into the play-offs which we are all eagerly looking forward to.
“It’s a fantastic season for us bearing in mind when I arrived last summer we had no players and no team.”
