Jens Lehmann expects to have his future at Arsenal clarified by the end of April.
The German's current contract is winding down and the club have so far failed to persuade him to pen an extension.
Lehmann is looking for a two-year deal, but Arsenal are understood to be only offering a one-season commitment.
The 37-year-old claims he has a tough decision to make, as he does not expect Arsenal to shift from their policy of offering players over the age of 30 long-term deals.
"We will talk soon, in the next week or two," said Lehmann. "I am not frustrated, it is business.
"I have always said I would like to play at Arsenal because I think I am certainly aware the team has potential.
"I can decide to be a part [next season]. It is my decision and I have to make the decision.
"I am on a one-year contract right now, why should I really be disappointed about another year?
"It is not about one year. If I should go somewhere else, then I would go for two years, but here it is only one year.
"It is always my decision. I can stay, of course I can stay, but I have to talk before. It is a tough decision I have to make."
