The Swiss defender is currently on loan with the Bundesliga club after falling out of favour at Arsenal. Djourou joined Hannover until the end of the season in the January transfer window, and the player's agent Marco Lichsteiner has suggested his player could stay in Germany.
The 26-year-old struggled to get a game at the Emirates Stadium, making just two appearances for the Gunners, but he's established himself as a first-team regular with Hannover.
And Lichsteiner thinks Djourou could end up staying with the Bundesliga club past the end of the season.
Speaking to German newspaper Bild, Lichsteiner said: "Johan and his family are very comfortable at Hannover. Johan fits well with the project. In the coming days, there will be a meeting with [Jorg] Schmadtke.
"Johan wants to have clarity over where he plays next season."
Hannover sit 10th in the Bundesliga, and Djourou has made nine league starts since joining two months ago.
And when Lichsteiner was asked whether his Arsenal player would be willing to take a pay cut to leave the Gunners and get first-team football elsewhere, the agent added footballing concerns will decide his future.
Lichsteiner said: "It's not not just about money."
Djourou wasn't getting a look-in at the Emirates Stadium, with Laurent Koscielny, Thomas Vermaelen and Per Mertesacker all ahead of him in the pecking order.
