Chesterfield boss John Sheridan hailed his side after they beat Port Vale 2-0 to maintain their lead at the top.
Second-half goals from Jack Lester and Deane Smalley settled a scrappy game as the Spireites edged closer to promotion.
Sheridan said: "I thought it was a very solid performance and we deserved to win the game."
He added: "We started very brightly and could have been two or three goals up in the first 15 minutes.
"We hit the ground running against a team I think will be in the play-offs. They have some good players but I don't think Tommy (Lee, goalkeeper) has had too much to do and the way we went about the game was very good.
"I'm pleased we kept a clean sheet and full credit to the players, they have given me what I asked for."
Port Vale caretaker manager Mark Grew felt his side were let down by some poor defending.
He said: "I'm disappointed at the way the goals were conceded, we have told the players this week that the biggest threat would be from crosses into the box.
"We got away with it a bit early on when they hit the post twice but I thought after that we did okay and we got into the game. We came in at half time and said the only way I felt they were going to score was from balls into our box.
"I'm disappointed with the way the ball came in, I didn't feel we pressured enough to stop the ball coming into the box. We all know what Jack Lester is about and he's had one chance and stuck it in the net."
