Bundesliga side Borussia Dortmund has stepped up efforts to sign Atletico Madrid's Spanish defender Oliver Torres, according to German media reports.
The club has accelerated its negotiations after failing to sign Turkish attacking midfielder Yunis Malli from Mainz 05, reports Efe.
Torres, 21, is contracted to Atletico Madrid until 2018, however he has not earned many caps since he returned back to the Spanish capital from loan to Porto last season.
The coach of Borussia Dortmund, Thomas Tuchel, is looking to support the team lines with new players to secure a leading position in the Bundesliga.
