The midfielder - who recently signed a five-year contract extension - was handed the armband this season by Ralph Hasenhuttl.
And it is a role which the Saints academy graduate treats with immense respect.
He told the club's website: "It's a huge honour. When I started out it was just to play for the first team and be a professional footballer.
"I think coming up through the academy, I captained various age groups and it began to come into my mind that it was something I always wanted.
"I knew that it wasn't something that was going to come my way straightaway and I think admittedly at times there have been moments where I've doubted whether that will actually happen.
"But it's presented itself to me now, it's come my way and I want to make sure that I'm the best captain for this football club and to make sure that I give as much as I can back to everybody there and to try and lead by example.
"I'm not going to let the opportunity pass me by. I want to be the best that I can in that role."
