Arsenal striker Yaya Sanogo insists he'll prove his worth to manager Arsene Wenger.
Sanogo is aware of the doubters.
He told L'Equipe: "Football is football, but it's a bit like going from sixth to third all at once.
"It takes time to adapt. When you come out of Ligue 2 and you end up in a duel with [Man City's Vincent] Kompany, it is not an easy task.
"In every aspect of my game I've evolved. When you train with great players every day, you progress. When you play big teams, it helps you 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 his worth.
"But Wenger just pushes me to continue my work will eventually pay off.
"They [pundits] criticise me. But I'm always there, I'll play, improve and score."
