The Blues dominated virtually from kick-off and on another night, Guidetti could have helped himself to four or five goals in the first half alone, though he only had a 24th-minute penalty to show for his efforts by the break.
The spot kick was awarded after Abdi Ibrahim was brought down in the box and the Swede, who had already missed a hat-trick of chances in the opening 20 minutes, tucked the ball away with aplomb.
City continued to squander chances in the second period but substitute Bunn finally sealed the game on 69 minutes with virtually his first touch when he turned in a Guidetti cross confidently from close range.
Guidetti then added a spectacular third, acrobatically volleying the ball into the net on 80 minutes, and completed a well-deserved hat-trick in the 90th minute, slotting the ball past the County keeper thanks to an assist by Ahmad Benali to seal a comfortable victory for Andy Welsh’s side.
