"I think there’s plenty more to come from me.
Obviously, I haven’t played in the Premier League yet, so once I get used to that I think I can kick on from there," he added.
Everton manager David Moyes, who previously tracked the England Under-21 international last summer, expressed confidence in the midfielder's potential to strengthen squad competition.
"Hayden is a promising young player who we’ve been tracking for some time, and I’m looking forward to working with him.
We’ve had a track record over the years of identifying players in the Championship who have gone on to do really well for us and been good investments.

We hope that will be the case with Hayden, too," said Moyes.
The manager noted that the acquisition fits into the club's established strategy of developing talented individuals from the lower divisions.
"He’s an England Under-21 international who will provide greater competition in midfield, which is something I wanted going into the new season," said Moyes.
Tottenham's Record Signing
Tottenham Hotspur finalized an £85 million deal for 21-year-old Portugal international Mateus Fernandes, who joined West Ham last August after earlier stints at Sporting and Southampton.
Spurs head coach Roberto De Zerbi praised the midfielder's tactical intelligence and direct experience playing in the Premier League.
"I’ve admired Mateus for a long time because he combines quality on the ball with the intensity and intelligence that are so important in the way we want to play.
