RB Leipzig defender Josko Gvardiol wants to join treble-winning Manchester City and has informed the club of his desire to leave, Leipzig sports director Max Eberl said on Monday.
Eberl said talks with City, who won their first Champions League title last month, were under way for a possible move of the 21-year-old Croatia international.
"Josko and his advisors have submitted the wish to us for a transfer to Manchester City," Eberl told Leipziger Volksnachrichten newspaper.
"We are in talks with Manchester. There is nothing more to say about it at this moment."
The back-to-back German Cup winners have seen several top players leave with Hungarian midfielder Dominik Szoboszlai's move to Liverpool on Sunday being the most recent one.
Defender Konrad Laimer has moved to Bayern Munich while France international Christopher Nkunku has joined Chelsea in the Premier League.
"I can understand the disappointment and concern of the fans," Eberl said. "No club and no coach in this world wants to lose players of this calibre."
"But we have been prepared for this and I can promise that we will have once more a good and exciting team."
