Anthony Joshua says negotiations for the Deontay Wilder fight must be "realistic" as he waits to find out whether he will face the American next.
The unified heavyweight champion is yet to agree a fight with the WBC title holder and could instead face WBA mandatory challenger Alexander Povetkin later this year.
Joshua insists he is not growing impatient at the lengthy talks for the Wilder fight as he believes there is enough financial rewards to satisfy all parties in a deal.
"It's not frustrated, it's just I've spoken about it, I've said my piece," Joshua told Sky Sports.
Asked about a potential deadline, he replied: "No, I'm still training, but in terms of a three-month camp, we've got until the end of the month, but there's still a few more weeks. It's just the nitty gritty I think.
"Everyone has seen the gold at the end of the rainbow, and everyone wants a piece. It's not a problem, there's enough in the pot for everyone to eat, but just be realistic and that's all it is."
Even if he defeats Wilder, the unbeaten 28-year-old admits he has plenty of options to consider in the future, including the returning Tyson Fury.
"There's so many out there for me to box and I've been doing it back-to-back, so it's no problem," he said.
"Then when I beat Wilder, the next question is - when are you going to fight Fury? The questions will never stop, and I just keep on knocking them down."
