An explosive second half saw the Sky Blues steal all three minutes with a 5-1 win over Colchester United.
Coventry had sat in the bottom three at half-time after trailing 1-0 to the Essex side, but goals from Best and Dann within six minutes of the restart put the Sky Blues ahead.
Eliott Ward scored a penalty after 78 minutes, Doyle scored two minutes later before Ward wrapped up the game at the death with his second penalty.
Chris Coleman made one change for the crucial clash against Geraint Williams' men..
Michael Hughes came into the side for Kevin Thornton, who was on the bench.
For the home side, former City defender Matt Heath was missing with a groin injury.
The Sky Blues had the opening opportunity when in the first minute, Best thread the ball through to Mifsud, who pulled his shot across the goal and wide of the far post.
Fox shot wide from a free kick and Michael Hughes shot at the keeper as Coleman's men threatened, before disaster struck for the Coventry in the 17th minute.
Chris Coyne played the ball through to Kevin Lisbie and although Schmeichel saved with his leg, the ball came out to Scott Vernon who tapped it home from six yards.
The goal incensed Coleman, who protested to the referee that Colchester were offside.
Coventry thought they had pulled one back on 40 minutes when Dann's shot looked to be heading in, only for Vernon to clear off the line.
Tabb tried again from distance moments later, only for the keeper to save before at the other end, Schmeichel saved well from a one-on-one with Lisbie.
But if Coventry had no luck in the first half, they certainly did in the second when Fox's ball was collected by Best with 49 gone and tapped home from four yards out - through the goalkeeper's legs. It was a fantastic start to the second period and it was a certainty that the team had experienced a roasting at half-time.
And there was jubilation amongst the Coventry fans just three minutes later with 51 on the clock when Danny Fox, on the edge of the area, curled a sublime shot into the top corner which gave Gerken no chance to make it 2-1.
Best was a constant thorn in the side of the Colchester defence and a particular threat in the air, heading wide on a couple of occasions and rarely beaten to the ball.
At the other end, Lisbie shot into the arms of Schmeichel with 71 gone, before Coventry were awarded a penalty when Duguid fouled Mifsud.
Elliott Ward stepped up to take the spot kick and made no mistake to make it 3-1.
The Sky Blues scored another when Doyle scored just two minutes later to make it 4-1.
At the death, Ward made it 5-1 with his second penalty of the game after Hines had been fouled by Balogh.
