Real Madrid midfielder Casemiro hailed coach Rafa Benitez, after the Sao Paulo product's future at the Santiago Bernabeu was secured.
The 23-year-old signed on at Real until 2021, despite a clause in his loan deal with Porto last season almost leading to a permanent stay in Primeira Liga.
Casemiro indicated he was happy with Benitez's arrival in the close-season.
"I learned a lot, also by working with Mourinho and with Ancelotti," he told Real Madrid's official website.
"Now with Benitez, I am sure that it will be an incredible year and I am going to continue working to play more and more. I am very happy.
"He is a great manager. He always wants his players to give their best, whether in training or in games.
"He likes people to approach things seriously and we are on the right path."
"It was a very important decision, for me and my family. Porto helped me a lot and now I return as a man and with more experience," he said.
