El Mundo Deportivo revealed that Dortmund are already planning a summer bid for Galatasaray winger Armindo Bruma.
Bruma is currently on loan at Real Sociedad, which has the option of purchasing his contract at the end of the season. If Sociedad chooses not to sign him, Dortmund will make a bid for Bruma.
The Portugese midfielder struggled in the Turkish Super Lig, but has done well during his loan spell in Spain.
Bruma was first sought after during his impressive youth days with Sporting Lisbon.
