Robin van Persie says he has no idea if he will be offered a new contract at Manchester United.
Van Persie has around 18 months to run on the four-year deal he signed on arriving from Arsenal in the summer of 2012.
The Holland striker said as far back as March he would like to stay longer, but no deal has been agreed.
He said: "It is not up to me. For the moment I am staying here for 18 months. That is it really. I can't look into the future. I don't know what is going to happen after that. We shall have to wait and see."
Van Persie averages better than a goal every two games for Unted but this season has scored eight times in 21 appearances - a return he admits is not good enough.
This year I have played something like 20 games and I have scored eight goals. I am not happy with that. I want to score more.
"Obviously we are not scoring enough goals, including me," the 31-year-old said at a corporate event at Old Trafford on Monday. "Everyone feels responsible. I do, definitely. This year I have played something like 20 games and I have scored eight goals.
"I am not happy with that. I want to score more. I will do everything, every day in training and during the games I will keep doing what I have been doing for the last 10 years to make those goals. It makes so many people happy, including me."
United are fourth in Louis van Gaal's first season as manager, but the new boss has had to defend his approach in recent weeks after criticism from some supporters.
Van Persie is well-used to his compatriot's methods from their time together with Holland, and he said: "We believe in him. We will still believe in him.
"The players have been working with him only four or six months, everyone believes in themselves, our team-mates and our staff. We are confident it will change.
"Him and his coaching staff and we as players are trying everything we can to win games, not only win games but win them in a nice way as well."
