Jean-Kevin Augustin's international future with France is in doubt after the RB Leipzig striker sent a text message to under-21 coach Sylvain Ripoll saying he was rejecting a call-up.
Augustin was excluded from the squad a year ago after a heated exchange during a game with Ripoll. He returned in March and scored twice in UEFA Under-21 Euro 2019 qualifying wins over Kazakhstan and Montenegro, and was selected for upcoming games against Bulgaria and Luxembourg.
Jesse Marsch has said he is looking forward to taking the "next step" at Bundesliga club RB Leipzig, with the former New York Red Bulls coach saying his eventual ambition is to return to the United States as national team coach.
Marsch, 44, left his role at ed Bulls last week to become assistant to new head coach Ralf Rangnick at Leipzig.
The former U.S. international had been touted as a potential head coach, but on Tuesday told reporters he was delighted to be part of Rangnick's staff.
