When and if he does that is up to him. In any case, it’s not the best sign in terms of work ethic when such a young player wants to leave at the first hurdle.
If he really wants to go to a club where he is seeded, he has to accept a loss compared to BVB in terms of salary and status. The only alternative would be to switch to a big club (Real, Chelsea, Bayern or similar) and then be loaned out for 1-2 years. But he can also have that at Dortmund.
Curious idea: Moukoko moves to Salzburg as part of the Adeyemi deal for a small sum, say 8 million. Dortmund secures this:
– Extensive buyback options at a level that is profitable for Salzburg, e.g. 24 million (or triple the transfer fee)
– Extensive pre-emption rights allowing BVB to pull the RKO before the player goes to another club
– A high resale percentage in case he doesn’t return to BVB from Salzburg. (25-30%)
Salzburg would have secured the next top talent and one way or another, the next million-dollar win is in the offing. The player has a regular place and can also prove himself internationally without pressure. Adeyemi has also proved that you can even come to the national team from Salzburg.
Dortmund prevents the player from losing completely. Because you will not want to go with him in the last year of the contract. Too high sums can already be achieved for this. A top club like Chelsea or Real would probably put 15-20m on the table for him if you look at what was paid for Vinicius for example.
