When asked whether it would be difficult to stay if the club were not in the Championship next season, Forrester told the London Evening Standard: "No, it wouldn't be difficult.
"The fans have been brilliant for me and the club is going in the right direction. It is a good place to be. This club has got a lot of aims and goals and they are pushing every player and that increases my chance of playing at the top.
"We will decide at the end of the season. I have spoken to the boss and he was great with me. He respects my decision and I have worked hard and tried to give the best performances I can."
