The midfielder will return to Inter after just 26 days at St Mary's, with the Premier League side questioning the player's commitment ahead of the new season
The Algeria international arrived at St Mary's Stadium on a season-long deal earlier this month, with Pablo Daniel Osvaldo moving in the other direction.
The South Coast club have agreed for the 22-year-old to return to Italy, stating: “The midfielder joined Saints for the 2014/15 campaign but, having failed to live up to the high levels of commitment expected of Southampton players, that arrangement has been cut short by the club.”
"Taïder, whose only first-team appearance came in the friendly against Bayer Leverkusen earlier this month, now returns to parent club Inter.
"Dani Osvaldo's loan arrangement with the Italian side is unaffected."
