The loan deal included a €16.5M fee, with Bayern having the option to sign Jackson permanently for €65M if he plays in 40 games for the German team. However, it's unlikely he'll reach this milestone, as he'll likely serve as a backup to Harry Kane.
Jackson's agent, Diomansy Kamara, has spoken about his client's intentions. In a recent interview, Kamara stated that Jackson's relationship with Maresca at Chelsea was strained, and that the transfer was a result of a "war of egos" between the two clubs.
Kamara also mentioned that Bayern executive Hoeness had reconsidered their initial comments about the transfer. He emphasized that Jackson's goal is not to play 40 matches, but rather to score 15 goals by December. If he achieves this, it's unlikely that Bayern will require him to play 40 games.
Kamara stated that Jackson sees Bayern as a priority and has no intention of returning to Chelsea. He believes that Jackson's future will be decided after he has a good season, and that Bayern is a top choice for him.
Jackson hopes to impress Bayern manager Vincent Kompany and secure his spot at the club. Chelsea has effectively ended their relationship with the striker, making it clear that he won't be returning to the team.
