Jamal Musiala is currently 21 years old, and he is having contract until end of 2026 with Bayern Munich most chances we will have extension before end of this contract because he already announces he doesn't want to leave club in near future despite few English clubs are interested to bring him in Premier League currently Barcelona is having no budget to have player like him so most chances if he will be leave German giants then we will have any English club for his future in soccer.
Investment wise Chelsea benefit from that guy because they had Musiala as free agent and never used him and yet they sold him well for 200k and yet Bayern see him like something they need even though when his injuries were mid and short term recovery until 2 years later they later gave him a good chance and his representing the club well. Considering his age, he will stay back as long as Bayern is ready to make use of him, anything outside here might not look juicy but he need to step up his game.
Liverpool is currently front-runner for his future, but situation is not clear because he is doing good at Bayern Munich and as they are having start of their season things are clearly indicating we will have good title race between top contenders in Bundesliga, but this future sensation is surely having good future he needs to do things wisely because any wrong decision can bring problems for his career.
If Liverpool get him good for him but that club sometimes is shit show, they have this habit of signing up a player only to be dumpnon bench pending till there is a substitution need or an injured player. Musiala is having a good time in Bayern. If he is not sure about the terms for playing, he better stay in Bayern and enjoy his life. However, maybe Liverpool will not exhibit such behaviors again since it does happened during the time of Klopp.
