Between 2011 and 2019, Musiala was part of the Chelsea academy system before he made the transfer to the Allianz Arena at the age of 16.
The main reason for the switch was the greater expectation of immediate first-team football, and that is what has materialised with the attacker establishing himself as a key player at Bayern.
A total of 41 goals and 29 assists have been recorded from 155 appearances in all competitions, including 13 such contributions coming in 2023-24.
However, speculation persists that a move to another club is not out of the question with his contractual situation currently a topic for debate.
Musiala is tied to Bayern until 2026, naturally leading to the German giants to commence their efforts to extend those terms for multiple more years.
At the same time, the Germany international is being consistently linked with other clubs with Liverpool, Manchester City and Real Madrid having all been credited with an interest in recent months.
Any transfer will be directly negotiated between the clubs involved, with any fee expected to be at least £80m if a transfer occurs this summer.
Nevertheless, according to the Daily Mail, Chelsea are keeping a watchful eye in the background as they hope for a lucrative bonus to come their way.
When Musiala was sold under the previous Roman Abramovich regime, it is claimed that a 20% sell-on clause was included in the deal that saw the then-teenager leave for Bayern.
If Musiala was sold for a minimum of £80m, which has been alleged to be his minimum value, Chelsea would stand to recoup at least £16m.
With Euro 2024 taking place in the summer, it is highly unlikely that Musiala would leave Bayern prior to that tournament, meaning that any unforeseen bonus funds would not go to Chelsea before June 30, the deadline for their next accounts.
That said, Chelsea will hope that one of European football's top clubs firm up their interest in Musiala at a time when they are required to generate as much money as possible in order to ensure that they meet the Premier League's Profit and Sustainability regulations.
