Lloyd Isgrove has put pen to paper on a one-year contract with Southampton.
The 20-year-old, who featured in the Southampton squad for the final two games of last season, has been with the club since the age of nine.
"Lloyd has shown a great deal of potential during his early years with the club, and he deserves this new contract in recognition of the hard work he puts in," manager Mauricio Pochettino told Southampton's official website.
"He has impressed me in his performances for the Under-21s and with his attitude on the training ground, having taken part in first-team sessions regularly last season.
"He now has the chance to demonstrate at senior level the qualities he has shown during his time with the academy and development squad."
