Dover manager Nicky Forster has praised the attitude of Michael Corcoran after removing him from the transfer list.
The Blue Square Bet South side have released four players in the last fortnight, prompting a rethink on the availability of the midfielder.
"He's been absolutely first class. He's applied himself really well," Forster told BBC Radio Kent.
"He's been a leader, even when he wasn't playing. It's a credit to him and the way he has responded."
Last week, chairman Jim Parmenter said the squad at the Crabble Ground was too big, with the midfield positions particularly congested.
Having released Sam Cutler, Luke I'Anson, Ross Kitteridge and Nathan Ashton, it enabled Dover to include 23-year-old Corcoran in their future plans and they took him off the transfer list on Thursday.
The trimmed down squad has increased morale amongst the players.
"The squad was too big," Forster said. "We had too many players sat in the stands which sometimes creates negativity.
"Players get despondent when they're sat in the stands but they're all vying for places now.
"There's real togetherness. It's something that we needed to do."
