"Everything that I heard about him was very impressive," Perez told ESPN. "The team was very impressed and enthusiastic. They really liked his personality - the way he interacts with the team, the feedback he gives and he is meant to be very easy to work with. The team was always very happy when they spoke about him.
"I had three great years with Nico and I learn a lot from him and now I look forward to learning a lot from Esteban. It is always good to learn things from different drivers. I have been very lucky to have very talented drivers next to me and so now having Esteban, it is a great opportunity to learn new things from a young driver."
