Coventry manager Steven Pressley believes his side have the defensive steel required to succeed in League One after shutting out Stevenage in a 1-0 win at the Lamex Stadium.
The Sky Blues could claim to have been the league's entertainers after scoring 13 and conceding eight during a three-game spell in August.
But they needed to show different qualities at Stevenage to claim a first win in three games after Leon Clarke pounced on Robin Shroot's poor back pass to put the Sky Blues ahead on 33 minutes.
And while Jon Ashton almost grabbed a point for Stevenage at the close, Pressley claimed his side were deserved winners.
"It was a brilliant team performance, full of energy, guts and courage," he said.
"I'm very proud as we've not always been able to win in that manner this season, 1-0 away from home, so it was a pivotal day for us as we've proved we can win this sort of game.
"I'm pleased for the players and the supporters, who were magnificent. We've only had one clean sheet this season so it was so important to get one with a mature performance from a young team.
"The goal came from our pressure on them and our desire to win the ball back. I want us to be an exciting team who play great football but we need to keep more clean sheets and we've done that.
"We have a brilliant group of young players here who couldn't work harder for this football club. I'm so proud of them all."
For Stevenage it is now six league games without a win and they sit in the relegation places, but manager Graham Westley insists they are heading in the right direction.
"The road back from losing ways to winning was never going to be an easy one and we've seen a number of performances recently that have been way below the right level," he said.
"There was much more I liked and some attacking intent as well. The error cost us and if you take that out of the equation it's a different result.
"We've looked way off the level against top-six sides this season but here we looked much closer to some top-quality opposition.
"We're taking strides and it's important when you're not getting results that you can see progress and you could see that. We will continue to do what we can to get a winning machine together.
"We're making marginal improvements and Rome wasn't built in a day. We're nipping losing habits in the bud and the desire of the players to change is evident to me now.
"There is definitely some momentum and I don't think we're far away from a good set of results. The desire and determination to change things is very much alive."
