A delighted Paul Cook reflected on a ‘special’ first half display from his table topping Spireites.
The Chesterfield boss watched on as his troops ripped Cheltenham Town apart in eight short minutes.
Dan Gardner and Ollie Banks both got on the scoresheet on their return to the starting line up.
Eoin Doyle and Liam Cooper netted during the Blues’ purple patch which took the stuffing out of the Robins.
Cook said: “We’ve had a lot of away games. We’ve had a lot of tough games. After Saturday, we got a lot of criticism.
“But you get used to it being the manager of Chesterfield. One week is different to the next. We were special first half.
“To come away from home and be as brave as we were in possession on the football pitch, the players deserve great credit.
“We had to dig in second half and they scored a poor goal from our point of view. Tommy (Lee) has made a couple of good saves.
“It was a good night for us. You always get a bit of stick when you get beaten. It’s how you bounce back and I keep saying the same things.
“I’ve got great faith in the players and you see the goals we’ve scored tonight you can easily see why.”
Cheltenham scored what proved to be little more than a consolation from a goalmouth scramble in the second half.
Mark Yates’s side piled on the pressure and Lee had to be at his best to make a handful of important stops.
Following the disappointment at Wycombe Wanderers, Chesterfield re-established a points lead at the top of League Two.
The Spireites’ closest rivals, Scunthorpe United, in second place were held to a 1-1 draw at home to Bristol Rovers.
Cook added: “We’re in a good position aren’t we? Top of the league and going to Wembley.
“All we’ve got to do is keep our feet firmly on the ground and look towards the next game. We’ve done that tonight (Tuesday).
“The lads came in Sunday morning. We put a shift in. We studied Cheltenham. We worked on our game plan and we were terrific.
“We were poor on Saturday, we’ve taken that on the chin and we go home happy tonight.”
