Sheffield United have released midfielder Michael Doyle after over four years with the club.
Doyle joined the Blades from Coventry City in January 2011 and made 188 league appearances for the club.
The 33-year-old helped the club reach the semi-finals of both the League and FA Cups and qualify for the League One play-offs three times in his time at Bramall Lane.
"I'm gutted. I've enjoyed every minute," he told BBC Radio Sheffield.
"I would have liked to have found out earlier, so I could have said goodbye to the fans properly. They've always shown me great respect and I hope I've done the same for them.
"I hoped to stay here, but I think I always knew there was a danger I wouldn't be."
The Blades lost out in the League One play-offs for the the third time in four seasons after being beaten 7-6 on aggregate by Swindon on Monday evening.
Doyle believes the team's promotion push was hampered by their poor form at home, where they won just 10 of their 23 matches.
"We dropped way too many points at home. I think some of the games we lost to some of the lower teams in the league really cost us.
"I'm sure they'll be looking to improve on that next year," he said.
The former Coventry man, who won one cap for the Republic of Ireland in 2006, is not sure where he will be next season.
"Although it's disappointing to be walking away from Sheffield United, it is exciting to see what else is out there," he added.
"It's a matter of seeing what is the best situation for me and my family. You never know where you might end up."
