Barca's members will vote for a new president on March 7, amid talk of Koeman eventually being removed for the winner's own coach.
But the Dutchman said: "I have not spoken with anyone. We have to wait to see who comes as president and meet his technical team. If I do not see an important future for myself, we are going to have a problem because I still have one more year on my contract.
"You don't know what can happen in the future. The day they called me from Barça, I was convinced to accept it, knowing that it was a difficult time. With difficulties to make changes in the squad and give opportunities to young people. Life is ups and downs, facing and solving problems.
"All clubs go through difficult times. A lot has happened to us this season. We are fighting to win things. In the end what counts is the field, the games, being with the group ... This is the best place for me, here until the last day to do my best for Barça. How long will I be here, it doesn't influence me. That Barça win is always the best."
