On Tuesday the Spireites made their first Proact Stadium appearance since last season's League One play-offs, going down 3-1 to Championship side Hull City.
However, the scoreline showed only one side of the story, the hosts taking the lead and looking the better side for long spells in the first half.
Goalkeeper Tommy Lee spoke to PlayerHD after the match and was impressed with what he saw from the ten men in front of him in the early stages.
He said: "I think in the first half we played really well, for 40 minutes we looked like the team that's just been relegated from the Premier League, we were creating chances and it was a positive start.
"Then in the second half I think the lads got a bit tired and maybe we should have changed the way we were trying to play but it's very early days - it was a test tonight and for 45 minutes we were the best team."
With fitness levels being constantly assessed and improved over pre-season, Lee spoke about the different expectations put on a 'keeper in the run up to a new season.
"It's not so much fitness it's more getting time on the pitch. I got 90 minutes tonight and I was a bit rusty to say the least, but the fitness will come.
"We've got a few games next week, which I'm looking forward to. I'll be working with Norm [Mark Crossley] and working on the areas I am rusty with - come Barnsley I'll be ready, and so will the team."
Throughout the match, Lee was tasked with playing shorter balls out from the back, an approach that the Spireites number one is looking forward to getting to grips with in the coming campaign, and in the match with Burnley on Saturday.
"It's a new style of play and it's not something I've been used to so far in my career," he said. "It's something I'm looking forward to doing and learning.
"Burnley are another team that have just been relegated from the Premier League, unluckily as well, and we need to test ourselves against those teams because Barnsley's going to be similar to these games."
