Sam Morsy captained the Spireites side on Saturday as a full Proact house saw Chesterfield lose 2-0 to Bristol City but confirm their position in the Sky Bet League 1 play-offs.
Goals in each half from Kieran Agard and Aden Flint saw the champions to an away win, but Rochdale's loss at Spotland inked the Spireites' spot in the post-season play-offs.
After the game Morsy reflected on a long but ultimately very successful season and gave credit to opponents Bristol City.
"It's been a tough season," he said. "We've been written off a number of times and we're delighted to get in the play-offs today.
"Bristol City are an excellent team, I thought we started off really well but they have good players in all positions. We're a little bit disappointed with how we played, but you should take your hat off to them, they've had a great season and they've shown why they are top of the league."
The result puts an end to Chesterfield's seven-match unbeaten run, but Morsy feels the defeat will galvanise the side ahead of next Sunday's match at Bramall Lane and the upcoming play-offs.
"I think it makes it easier actually," he said. "The players never want to lose but when we do lose that's when we come out fighting again. If we'd gone unbeaten maybe a little bit of complacency would have come in, so it could be the kick up the backside we need.
"If it had gone down to the last game of the season I'm sure it would have been an interesting one, but we're delighted to have taken care of it today."
Morsy looked back on his time at the club, a period that has been gold-lined after winning the League Two title this time last year.
He said: "First and foremost the goal was to get into League One, during last season a lot of people told us our style would suit League One better - and that's something we really started to believe in.
"When we started off in League One and the momentum was great and we were going well that's when we actually thought we had a chance.
"We haven't really looked back, we've had a few ups and downs, but we haven't really looked back."
