The 21-year-old joined the north London outfit from Auxerre in July 2013, but is yet to find the back of the net for the club, a point which has caused great consternation among Arsenal fans.
Having bagged four goals in a pre-season friendly against Benfica, there was renewed optimism that Sanogo would make the step up in the Premier League, but this has thus far not proven to be the case.
However, manager Arsene Wenger has consistently backed the Frenchman, and Sanogo believes he will soon repay his compatriot’s faith.
“Football is the football, but it takes time to adapt,” he told L’Equipe.
“When you come out of Ligue 2 and you end up in a duel with [Vincent] Kompany, it is not an easy task.
“On all aspects I’ve evolved. When you train with great players every day, you progress. When you play big teams, it helps gain experience.
“The fans expect me to score more, but once the first one goes in they’ll come.
“At 21, it’s not easy to play striker at Arsenal. You have to fight every day to prove your worth. But Wenger just pushes me to continue my work will eventually pay off.”
With Olivier Giroud sidelined for four months due to a leg injury, Sanogo is likely to have a chance to prove himself, with new signing Danny Welbeck also vying for a spot upfront.
