On 5 July 2010 he signed his first professional contract, agreeing to a three-year deal with Grenoble. Following Grenoble’s fall to the Championnat de France amateur 2, the fifth division of French football, due to financial problems in 2011, Saphir joined Italian club Bologna. On 16 January 2012, he made his first start in Serie A in the 1–1 draw against Napoli.
On 6 August 2014, Taïder joined Premier League side Southampton on a season-long loan, in exchange for Dani Osvaldo. He played his only match three days later, replacing James Ward-Prowse in the 61st minute of a 1–0 home friendly defeat to Bayer Leverkusen.
Saphir played for France at U18, U19 and U20 level. On 26 March 2013, he scored on his debut for Algeria against Benin. At the 2014 FIFA World Cup, he played the entirety of Algeria’s opening group match, a 2–1 defeat to Belgium. He did not feature again until the last 16, playing the first 78 minutes of a loss to Germany by the same score after extra time in Porto Alegre.
