According to the Ligue 2 club's chairman, Guy Cotret, Sanogo will not be given the opportunity to return to his homeland in 2013/14 because he will be integrated straight into the Gunners first-team.
Arsene Wenger has been so impressed with the 20-year-old front man that he feels there is already a place for him in the senior squad at the Emirates Stadium.
Sanogo is said to have already passed a medical and will reportedly sign a four-year deal with Arsenal, tying him to the Premier League outfit until 2017.
"He will only loan him back to us if he considers the player is not ready to join his team after the preseason preparations," confirmed Cotret in an interview with a French radio station. "Otherwise he will not loan him."
With eight goals in seven appearances in Ligue 2 this season - four of which came from the substitutes' bench - the France U21 international has a mightily impressive goalscoring record, and Arsenal fans will be hoping that Wenger has unearthed another gem in the years to come.
