Sporting Lisbon defender Eric Dier will not be extending his stay with Everton.
The 18-year-old Cheltenham-born centre-back, who moved to Portugal at the age of six, had been on loan at Goodison Park since January 2011.
However, after failing to make a single first-team appearance for the Toffees, Dier will now return to Lisbon.
Everton boss David Moyes told O Jogo: "We wanted him to stay with us. We knew he wanted to be in the first team, even though there would be little chance.
"Maybe [coach Ricardo] Sa Pinto and Sporting have other plans for him."
Dier has represented England at Under-19 level.
