“I want to tell the masses that whenever I wear this shirt, I will do my best, I will give everything I must take to the top, where they deserve to be.”
The transfer was officially announced by Everton at 00:15 GMT after sending a deals paper to the Premier League, allowing the extension to 01:00 GMT to complete the deal.
