The young Scot completed successful loans at Crystal Palace and Sheffield United, deputised for Tim Howard against Manchester United and also signed a long term deal at Everton in a breakthrough season.
"I am back trying to get a bit extra before we start the pre-season, which is a very hard time for the players," he told evertonTV.
"The way things stand I should be number two this season. I'll be looking to push on and hopefully get the number one jersey off Tim, who has had a phenomenal year to be fair to him - and it's continued playing for America.
"So it is going to be a hard year but I am looking forward to it.
"The team is going up and up and up so who knows where we will end the season."
