Borussia Dortmund are consistently linked with a bid for Ciro Immobile, who is co-owned by Torino and Juventus.
The rumours had already appeared in the Italian and German papers several weeks ago, but have stepped up a gear.
According to calciomercato.com, Borussia directors are travelling to Turin in order to discuss terms with the two clubs.
Immobile grew up in the Juventus youth academy, but has really hit form this season on loan at Torino with 17 goals in 27 Serie A games.
The 24-year-old has a strong chance of going to the World Cup, even though he has only one senior cap to his name, and Borussia Dortmund are eager to strike a deal before his price-tag levitates.
Immobile is believed to be worth in the region of €12m.
