Kevin Mirallas quit Everton for Olympiakos last week due to broken promises.

Mirallas completed a loan move to former club Olympiakos last week and will stay in Greece for the rest of the season.

The Daily Star says he was told he would play a far more prominent role in the Toffees' campaign but remained out-of-favour under ex-boss Ronald Koeman.

A source said: “He was unhappy in Everton, even from the start of pre-season.

“He understood that he would not be the first choice, although when he signed a new contract, he was led to believe that he would be an integral part of the team.

“He had no problem with Sam Allardyce, because he is a new coach. He didn't have a problem with Big Sam at all, more with the previous boss and the board."
