Coventry City manager Steven Pressley has praised his side's fitness and the defensive resilience after the 1-0 victory over Sheffield United.
The Blades dominated the early stages and Ryan Allsop was forced into a good save to deny Sheffield striker Michael Higdon.
From then on, the Sky Blues dominated proceedings at Sixfields and were rewarded for their performance when Jim O'Brien headed home a Ryan Haynes cross in the 76th minute.
Having lost the first two games of the season against Bradford City and Cardiff City, Pressley has praised his side's mentality.
Pressley said: "Having lost the first two games, today presented a really big test for us and I thought we responded brilliantly.
"Our application was excellent and we've seen us grow into the system. When we play like we did today, we can be a very good side and we've set a standard.
"I don't think we would have won that game last season but we saw it out. We were brilliant at the back and were rarely troubled throughout the game.
"It is only one step in the right direction but you could tell we've got the makings of a very good side here and it has really lifted the place."
Ryan Haynes came into the side to replace the injured Danny Pugh at left wing-back and Pressley has praised the young defender's performance.
He added: "I thought Ryan was outstanding today. He is a smashing young player and I've always said the Academy players are the heart beat of the club.
"We've got to trust young players at this football club but also, they've got to be up to the right quality to play for this football club and Ryan was today.
"I think you've also got to applaud the performances of the summer acquisitions today. The way the team worked for each other shows we've brought into the club the right type.
"We'll come in tomorrow and recover from today's game and then refocus on the Barnsley game."
