Arsenal's out-of-favour defender Philippe Senderos admits he may need to quit the club in order to find first-team football.
The Switzerland international, who spent last season on loan with AC Milan, is yet to make a Premier League appearance this term.
Senderos is frustrated by his lack of first-team action and insists he is not closing any doors when it comes to the January transfer window.
Everton were in talks for Senderos over the summer and David Moyes may decide to renew his interest come the New Year.
"I need to seek a solution as I'm not playing for Arsenal," conceded Senderos in the Sunday Mirror.
"A change of clubs in the winter is an option - I am keeping all doors open.
"This is a difficult time. It is like a test that I have to come through, but I believe in God and have to stay strong."
