Kelvin Davis has signed a new contract at Southampton, keeping him at St Mary's until 2016.
Davis, 36, whose old deal was set to expire at the end of next season, has now extended his stay at the club through to his testimonial year, having first joined in 2006.
The Saints' club captain was delighted with the news and singled out praise for chairman Nicola Cortese, who he believes has made a significant impact since arriving on the south coast.
"When I first came to this club, to say that I would have been here for this period of time is something that I would have dreamed about," Davis told the club's official website. "For that dream to have materialised and for me to be feeling good is something I am really, really pleased with.
"I've seen a few things - a few ups and downs - but since Nicola Cortese arrived with Markus Liebherr [former owner], the club has been on a journey. Little did I know the success, the drive and the constant improvements that would come once they got their teeth into the job. If those guys hadn't been here then I certainly wouldn't have been either, and it's great that I've been a part of that under Nicola's leadership. That has allowed me to fulfil my dream.
"I don't think anyone connected with the club can doubt what has been achieved here. Nicola in particular has been a massive part of my situation and me being at this club. He's made promises in the past and, from my point of view, he has delivered even more than he promised in the outset. He's the sort of guy who believes that achievements are to be rewarded, and he's certainly proved that with myself."
Davis has been limited to just nine appearances for Southampton this season, but manager Mauricio Pochettino says he still has a vital role to play for the club.
"As club captain, Kelvin plays an extremely important role at Southampton," he said. "His presence in the dressing room is second to none, and his experience has proved to be vitally important to the club as we look to achieve our aims.
"He has been a massive part of this club during his six-and-a-half years here, and there are few things in football that he hasn't seen so far in his career. Every successful team needs to have characters and people like Kelvin, so I'm delighted that he has committed himself to the club for a further three-and-a-half years."
Davis is Southampton's current longest-serving player, having made 283 appearances for the club since joining from Ipswich six-and-a-half years ago.
