The former Besiktas striker has had a slow start to his Premier League career.
“It's not easy to adjust to a new environment, a new atmosphere, new friends even a new house," he told Haberturk.
“Even though I was born in Europe this situation is different."
“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.
“He always talks to me. I've zero problems. He told me that when I fit into the league and team, I'll be a regular starter."
Tosun added: “I've zero interest going back to Turkey at this point.
“I'll show everyone in England who is Cenk Tosun.
“I have a dream. I never quit a work before completing it."
