Despite his struggles, Tosun has vowed to "show everyone in England" his capabilities up front.
"It's not easy to adjust to a new environment, a new atmosphere, new friends even a new house," the 26-year-old told Turkish outlet Haberturk. "I moved from Turkish league which the league I'm playing for years to the toughest league in the world. It's hard to adapt. Sam [Allardyce] told me that too.
"I've just started to know my teammates. In Besiktas, my teammates knew where I was going be on the pitch before they passed. They knew what I was going to do. In here they'll learn that too in time.
"I've zero interest going back to Turkey at this point. I have a dream. I never quit a work before completing it. I'll show everyone in England who Cenk Tosun is."
