"So it is easier to develop and in time I think there will be more to come from me.
"In Ajax we played 4-3-3 and I was a left winger. But here we play 4-4-2 and there is more defending to do, so that part in the beginning was a little bit difficult. I am doing better now but there is still some things I need to improve and I talk about this with the manager."
He added: "I hope I reach 10 Premier League goals. I'm now on three, so I will have to get seven more. If I can get even more than that it, then it would be a very good first season for me."
