Will Still said Kuryu Matsuki will have made people "stand up and notice him" following his spectacular goal at Norwich City.
Japanese midfielder Matsuki sealed Southampton's 3-0 EFL Cup second round win with the goal of the game and his first for the club, a long-range, left-footed strike into the top corner.
Matsuki joined Southampton last summer from FC Tokyo, spent 2024-25 at Turkish sister club Goztepe and returned to St Mary's for this season.
His appearance at Carrow Road was his third for Southampton so far, with all of them coming as a substitute.
