Leighton Baines and James McCarthy are both in contention to make their return from injuries against Swansea City this weekend.
Baines last played against Middlesbrough two months ago, while McCarthy had been sidelined since the draw at Manchester City in August. Both have been training with the group and Koeman is ready to welcome them back to the fold.
Everton will definitely be without Gareth Barry on Saturday as he sits out the game through suspension as a result of accumulated five bookings.
The setback of losing the midfielder has been offset by the return of Idrissa Gana Gueye who is back available after serving his own one-match ban.
