“Talk to the manager and [director of football] Marcel Brands, I had a very good feeling with the club and I think it’s a place where I can continue to evolve.
“The manager, with his ambition and what he has won in the past, is important and we will be looking to move forward and compete with the best clubs. I think a club of this magnitude has all the potential. to be up there.
“Everton are a very big club and the main goal is to push and get back to the top of the table. I want to work hard on the training ground and do my best for the club on the pitch.”
