Zlatan Ibrahimovic is without a contract after the coming season and has been linked to AC Milan, Manchester United and Galatasaray.
"It may have been the last game of my career at PSG," said Ibrahimovic.
"This week I need to make an important decision"
Ibrahimovic sparked a frenzy following PSG's win against United in the International Champions Cup on Wednesday, when he claimed his next club would be a surprise.
"Where I go next, it will be a surprise, a very big surprise," he said. "I'm very happy at PSG. You don't see that on the field?
"I have another year on my contract with PSG and I am very happy.
"Things are getting better. We are a strong team, we can do much more than we have been doing so at the moment but I am very happy."
