Obertan joined Toon in the summer after three frustrating years at Manchester United.
"When I was a kid growing up, English football was one of my main passions," he told the Sunday Sun.
"Manchester United were my main team but of course, Newcastle were famous when I was growing up too. It was the years when Kevin Keegan was manager and all French people followed (David) Ginola.
"I have always had an interest in English culture. I did foreign languages courses for a year at university before I gave up to play football. So I can speak English, French and I learned Italian in my spare time. I can speak a little bit of Spanish too but I have always been interested in English.
"I watched movies and TV programmes in English my entire life so it made sense to go and learn the language. Plus I had learned it at school and did well there.
"The only thing is, when you come to England you have to get used to the accent. At university it is easy to understand but when you have the Geordie accent or the Manchester accent, it is a bit different."
