Tunisia's World Cup captain Wahbi Khazri has ended an underwhelming spell at Sunderland by joining Saint-Etienne.
Khazri enjoyed a fruitful stint on loan with Rennes last season, scoring nine times in 27 appearances as they qualified for Europe.
That form, alongside two goals and two assists in Russia, encouraged Saint-Etienne to sign the winger on a four-year deal after paying an undisclosed fee, reported to be £6 million ($8m) rising to £9m ($12m).
The 27-year-old joined Sunderland in January 2016 from Ligue 1 side Bordeaux, having spent two seasons there following a move from Bastia.
