Chamakh admits he's never been regarded as a regular scorer.
"Personally, I've never been a great goalscorer, I've never scored more than 20 goals a season, but it's up to the manager as to how he uses his players," he told Arsenal.com.
"For me, if I can weigh in with 15 to 20 goals, it would be a very, very good season. Whatever happens I hope to continue my progress, which went really well under Laurent Blanc [at Bordeaux] and long may it continue.
"It's gone really well with the set-up here, I hardly knew anyone when I arrived but they've all made me feel very welcome. It has been easy to settle in and this has allowed me to express myself and that's very important.
"Personally, I'm happy. I can do better but yes, I am happy."
