Borussia Dortmund are keen to sign Red Bull Salzburg's French central defender Joane Gadou, media reports said on Tuesday.
The 19-year-old has already agreed terms with the Bundesliga side, the reports added.
The two clubs are discussing a fee, which could be around 20 million ($23 million)
Gadou joined the Austrians from Paris Saint-Germain's youth ranks and became a key player.
His signing would be the first under new Dortmund sporting director Ole Book. Dortmund are not renewing centre back Niklas Süle's contract, which ends in June.
