Talking about next season Challinor said "League Two will be different next year the teams that are coming into it certainly from the National League, Wrexham and Notts County, are strong teams.
"The teams coming down are a bit of an unknown in terms of where they currently sit and what their focus will be.
"Then you've got Doncaster Rovers, big investment for them, and Gillingham, who invested in January and will likely go again, so it'll be a different dynamic next year.
"As you say our start was a tough one and in hindsight, you can look back and reflect and say did that cost us but I think regardless, you're judged over 46 games and we got 79 points.
"So we know next year that we're going to have to get upwards of 80, maybe even higher than 83, to make sure we guarantee ourselves in place in that top three."
