Southampton midfielder Calum Chambers has signed a four-year contract extension with the Premier League club.
The 18-year-old academy product made his senior debut for the Saints last season against Stevenage in the Capital One Cup.
"It's fantastic - it's like my dream, really," Chambers told the club's official website.
"I've been here since I was seven and I've been treated really well so it means the world.
"I'd like to push myself into the first team and to prove myself there."
Southampton return to pre-season action on Saturday when they face Celta Vigo in Spain.
