Persistent speculations, promoted by Turkish journalist Burhan Can Terzi, concerned a very imminent transfer of Jamal Musiala from FC Bayern to Galatasaray Istanbul. Galatasaray publicly denied the claims twice, officially stating that the rumors were untrue and suggesting that those spreading them were engaged in a campaign against their transfer activities. The journalist was accused of spreading misleading information and was temporarily detained by Turkish authorities.

Burhan Can Terzi claimed that Galatasaray had reached an agreement with Jamal Musiala and that the German international was expected to arrive at the club soon. Terzi stated during one appearance that he was very certain about the information. On July 31, Galatasaray officially denied the story, publishing that the claims about Musiala's transfer were not true and that false information continued to circulate after the denial. Terzi later apologized to fans for raising expectations but maintained that he received the information from different sources. In one appearance, he publicly questioned Oktay Ercan, owner of Belgian club Westerlo, asking if Ercan had told him that the deal for Musiala was done and that the player would arrive at Galatasaray the following week.

Galatasaray has published a statement categorically denying a rumor about the arrival of Bayern Munich attacking midfielder Jamal Musiala. The Turkish club denounced the information as being false and claimed these speculations are spread to harm its transfer market activities. Galatasaray added that individuals and media responsible for these speculations had made similar unfounded claims last season, and noted that transfer operations are conducted with great rigor and confidentiality.

According to Fabrizio Romano, the management of Bayern Munich does not intend to release Jamal Musiala and continues to trust him despite his serious injury. Sky Sport Germany reported that the transfer rumors are not true and that there have been no talks between Galatasaray and Bayern Munich for Musiala. It was also stated that the German player is certain to play for Bayern Munich in the new season and will continue his career at the Munich club.
