"He is the coach that has got the best out of me," the 31-year-old said. "I know him well, he knows me well.
"I'm hopeful I will get back to that level we had before, this is the idea. He is someone who helps me, knows my game and how to get the best out of me.
"I am very happy to be here. It's a wonderful club with a wonderful stadium and it is really a fantastic experience. I hope with time that this team will be able to achieve all the goals they can."
