The former Gunners striker admits that he struggled to compete alongside Robin van Persie and says that his only option was to leave the club in order to find first-team football
Having joined Arsene Wenger's side in July 2010, the Moroccan initially impressed after scoring 10 goals in his first 21 appearances for the club but a return of just one more strike in the subsequent 23 games of his first season was the start of his decline at the Gunners.
"They're a team I always followed, a team I've loved, but that page has turned. Now it's important to feel wanted and to show what I can do," Chamakh told The Observer.

The striker made only 19 appearances for the north Londoners in his second season and was loaned out to West Ham in his final campaign with the club.
Palace signed Chamakh in August and the 30-year-old has scored four goals in 22 Premier League games this term.
"It was difficult but we had Robin [van Persie], a player at the height of his powers, the best in the Premier League at the time," Chamakh remarked of his time at Arsenal. "He had a season that was completely crazy in that first year I was there, a season no one could have predicted, and got better.
"The manager only played with one up and Robin was never injured, he scored goals every week, so how was I going to play? I knew I wasn't in the side because he was better than me. That was the reality. I accept that. He's just a better player.
"Of course it was frustrating, seeing the team win virtually every week but playing very little part in making it happen.
"I hadn't moved to Arsenal to sit on the bench but I knew why it was happening. You ask yourself questions and, in the end, it was easy to see I had to leave. That was the only answer."
