"I would like that when you come into a new team, you could push a button and say 'this is a change and we move on', but that's not how it is. It takes a little getting used to. I have always been able to count on the confidence of the coach, my teammates and the people at the club.
"I took a rhythm and I got to know them. It was not easy, it was not just a question of arriving and giving the maximum. I felt an improvement every week."
