Seamus Coleman, Tom Davies and Andy Lonergan have been offered new contracts by Everton.
The three players, whose deals were all set to expire at the end of the month, will each have the chance to stay on at Goodison Park after being offered new terms.
The Blues have confirmed that Yerry Mina and Andros Townsend have not been offered deals and that Asmir Begovic will also depart, saying the goalkeeper turned down an offer of a new contract. Mina and Begovic had already confirmed their departures. But it was unclear what would happen over Townsend.
