"It is a great group of lads there, great staff, I've settled in nicely," Keane said. "I'm really looking forward to going back now and cracking on.
"Obviously it's been a long time coming sorting the move, it's been in the back of my mind all this year really, so to get it over the line was a relief."
When asked if Everton could compete with the top six teams in the Premier League Keane said: "I don't see why not, obviously they are spending a lot of money as well.
"But, look at the players we've brought in," he added. "I see the quality of the squad every day in training, and there is no reason why we can't go into every game thinking we can win it."
