Southampton's 19-year-old defender Tom O'Connor has signed a two-year contract extension, keeping him at St Mary's until June 2021.
Kilkenny native O'Connor, who is enjoying a fine season as part of Radhi Jaïdi's Under-23s, has taken on the captain's armband this season, as well as a new role at centre-half, having first joined the academy in 2015.
"It feels really good," the Irishman began. "I've been here nearly five years now, and I've enjoyed every moment. I'm delighted to sign a new deal and hopefully I can keep improving.
"My target was always to reach the first team. The next step is the most difficult step, but I'm working towards it.
"Seeing all the academy graduate names on the teamsheet recently gives you a great boost and shows that the new manager really values young players.
"You know if you're performing, and working hard, you have a chance of being noticed."
