Southampton have sold teenager Alex Jankewitz to Swiss club Young Boys for an undisclosed fee.
The Switzerland-born midfielder, 19, joined the Saints' academy in 2018 from Geneva-based side Servette and went on to make three first-team appearances.
Jankewitz was shown a red card in the early stages of the 9-0 Premier League defeat at Manchester United in February - the last time he played for Ralph Hasenhuttl's side.
A statement on Southampton's website read: 'The club would like to thank Alex for his efforts during his time as a Southampton player and wish him well for the future.
