The 20-year old French striker joined the Gunners from Auxerre in the summer and has so far made two appearances off the bench for the North London club.
Sanogo, who has had goalscoring success with French youth teams, is loving his time at Arsenal but knows he has to get stronger in order to be a threat in England's top flight.
"I think I'll have to toughen up and improve my strength, that's part and parcel of such an intense league as the Premier League, as well as getting used to the step up, which it is from the French league," Sanogo told the club's official website.
"My main aims are to come here and learn, progress in the game and learn my trade with such great players. Now I'm training with them, I'll gradually make progress."
"But I will need time, it's a new way of life, a new league and it will take time to adapt. It's something I will manage."
