The England centre-back signed a contract keeping him at Goodison Park until 2017 during the week and he admits he would like to remain on Merseyside even longer than that.
"I hope I do," he told the club's official website. "I love being here and the club have obviously not minded extending my deal for another two years so I'm looking forward to the future.
"I really enjoy playing here. It wasn't a long discussion to extend my contract - I was delighted to do so. I'm proud to be part of this club and especially if we keep going forward the way we are at the moment, maybe there'll be another contract extension in a few years to come.
"It was really hard for me to leave Sheffield United having come through the ranks and having been given me my first big chance there, but Everton is a massive club. I spoke to my family at the time and we knew it was the right move to make.
"When I came, I was a little bit of a utility player - I used to play midfield, right-back and centre-back without really nailing down a position.
"But with the guidance not only of the manager and his coaching staff, but the players around me and the more experienced ones, I managed to settle down at centre-half and it's not been too bad since then."
