Cheltenham defender Shane Duff has penned his new contract at Whaddon Road.
The 24-year-old has put pen-to-paper on a two-and-a-half-year deal.
"At the end of this contract I will be 27 and hopefully my best years will still be ahead of me," he told the Gloucestershire Echo.
"For a centre-half, they say you reach your best years at 28 or 29 so I still have a lot of learning to do and I can still improve.
"That is good for me and the club."
