Oldham manager Paul Dickov has released nine players but backed his young squad to progress next season.
Striker Reuben Reid and defender Zander Diamond head the list of players who must now look for new clubs.
Meabnwhile, Dickov has informed nine more out-of contract players that he wants them to stay at Boundary Park.
"Everyone wants results straight away but, with a young squad, you're not always going to get it."
Paul Black, Ryan Brooke, Djeny Bembo-Leta, Matt Carr, Keanu Marsh-Brown, Phil McGrath and Josh Parker have also been told they are free to leave the League One club.
Kieran Lee, Robbie Simpson, Chris Taylor and Filipe Morais are among the players who will be offered new deals later this week, but Dickov has said he will allow Taylor to leave if he receives a suitable offer from a Championship club.
The Latics battled against the drop during the second half of the campaign before eventually finishing 16th in League One, 11 points clear of the relegation zone.
"In a way, with the injuries we've had, it's been an achievement to stay up with the youngsters we've had, but we're looking for them to kick on now," added former Manchester City and Leicester striker Dickov.
"People come up to me and say I can relax now, but this will be my busiest time.
"I've got to reflect on where we went wrong on a lot of occasions this year and put that right, and I've also got to try and get players through the door."
