Paul Cook lauded the impact of Jay O'Shea after the Irishman rifled home an unstoppable 52nd minute opener to inspire the Spireites to a comfortable 2-0 win over in-form Bristol Rovers.
After a rather subdued opening period, the Dublin-born youngster latched onto a loose ball on the edge of the box before dispatching a rasping drive into the top corner and propel Chesterfield to within nine points of the League Two play-off places.
Ivorian international Armand Gnadnuillet also capped an imperious display, weaving his way past a bamboozled Rovers skipper Tom Parkes to slide home a deserved goal and ensure all three points remained at Whittington Moor.
"First 15 minutes we were awful," Cookie revealed.
"We never got going, we were sloppy. Tommy Lee makes a world-class save and if that goes in, I wonder what would have happened.
"All of a sudden you're 1-0 down, the crowd are getting on your back because you're not playing well. But from there, in players like Jay O'Shea we know if we get them in the right areas they will hurt people.
"He needs to shoot more, he needs to show our fans a little bit more of that. His goal was unstoppable and obviously the second goal from Armand is a fantastic goal.
"From there, the confidence grows and everyone goes home happy."
It put an end to a miserable barren run in front of goal for the Liverpudlian's side, who had only breached the opposition's resistance once in the previous five encounters courtesy of Dagenham & Redbridge skipper Abu Agogo's own goal in the 1-0 win at Victoria Road.
At the other end, however, the Spireites have only conceded five goals in 10 games since transfer-listed Neal Trotman returned to the side following a 2-1 defeat against Wycombe Wanderers at Adams Park and Cook is fully aware his side have got solid foundations to build upon.
"We didn't concede many chances again," he added.
"Defensively we looked fine, I thought Richard Brindley was excellent. But goals must come from all areas of the pitch, our set-piece delivery is excellent.
"Conor Townsend has fantastic desire and sometimes, I feel, we are not going in with that hunger and desire to score.
"When things aren't going well, you are looking for a set-piece, penalty or bounce of the ball but today we got a lift off a fantastic goal from a very good player."
Cook plumped to freshen things up in attack in an attempt to give his side a ruthless streak, naming 37-year-old striker Jack Lester alongside Gnanduillet with Marc Richards dropping to the bench.
The former Port Vale man hasn't scored in nine games, but stepped off the bench alongside the returning Tendayi Darikwa as competition for places intensify with a squad nearing full fitness again.
"Going forward, goals come from all areas of the pitch.
"You can't put your strikers under immense pressure and say if you don't score, we won't win.
"We've scored two goals, we're delighted with the win. We move on. There's nine games to go, a lot of football to be played and we're still in the chase."
