Borussia Dortmund midfielder Shinji Kagawa's future remains clouded after the Japan international missed the squad for a second straight match.
The 29-year-old did not participate in his club's 4-1 win on Sunday over RB Leipzig in the opening stage of the Bundesliga or its 2-1 extra-time victory at Greuther Fürth in the first round of the German Cup.
"I can't worry about external factors, I have to focus on myself," Kagawa said after training on Monday, according to Nikkan Sports. "I may stay, I may leave. Only God knows."
The Samurai Blue star and two-time World Cup participant has reportedly attracted interest from Spain's Sevilla, France's Olympic Marseille, and Turkey's Besiktas.
Kagawa is under contract with Dortmund through June of 2020.
