Chesterfield assistant manager Leam Richardson was justifiably proud of his players following a 2-1 win at Leyton Orient.
Romuald Boco fired Chesterfield into a seventh-minute lead when firing a superb goal low into the left-hand corner to stun the home side.
Orient eventually came to life but found Spireites goalkeeper Tommy Lee in excellent form and although the visitors defended deeply after the break, they were dangerous on the counter-attack.
Eoin Doyle illustrated that when he slipped between two defenders in the 78th minute to double Chesterfield's lead before Orient substitute Darius Henderson pulled a goal back eight minutes from time.
"It was a very good win against a side who are a very good team," Richardson said.
"They are well set-up by Russell Slade and they keep the ball very well but having said that, we set our side up to come here and win the game.
"It was a fluid game, there were chances at both ends and it was important for us that we got our season off with a win.
"Although we got promotion last year, there were some tough times and we expect that on occasions again this time.
"It's a tough league and an unforgiving league because there are some very good players and very good teams in this division.
"So to get a win against one of those excellent sides is very encouraging. We'll take the points, keep our heads down.
"We have a lot of self-belief within our squad and individually they know they can handle themselves and do well.
"To get the first goal at any level is important and to get that on the opening day and away from home is superb.
"Any points away from home are good value and so to get all three is excellent value."
O's boss Russell Slade admitted it was not the start he had wanted.
"We are all disappointed, the players, the staff and the fans," Slade said.
"You want to register some points as soon as you can. I don't think that there was lot in the game, I have to say.
"We had chances in the first period and they got a very important first goal, but I thought we had three chances off the back of that to get back in the game.
"But then we just kept plugging away, but it was not until we made changes and Henderson came on late that we made an impact.
"It wasn't until then that we looked as if we might get something out of the game.
"I was really disappointed with the manner that we conceded both goals, hesitation for the first one and then we've not had a good line for the second one and what was a hopeful pump forward has cost us dearly.
"The substitutes did have an impact but at this stage, it's all about them getting minutes on the pitch as they fight to get their full fitness because it's a long season and the timing of when they came on the pitch was important."
