The 23-year-old impressed in Ligue 1 last season, and is expected to leave the club following their relegation to the second tier of French football, but he is yet to decide whether to make the switch to England.
"I have offers, notably from Freiburg in Germany and in England from Swansea," Bakambu told France Football. "I am hesitating between the two.
"I am giving myself two to three days to decide, no more. I know that at Swansea I might not be first-choice striker. There are several things to consider, not just the prestige of the club.
"But I am flattered. I'm at an age where I need to play. Crystal Palace are also interested, I think it will be between those three."
Bakambu scored seven goals in 31 league appearances last season.
