Borussia Dortmund could turn to Lazio coach Vladimir Petkovic should Jurgen Klopp be seduced by another club.
The 45-year-old German has become one of the most sought-after managers in Europe after guiding Die Borussen to back-to-back Bundesliga triumphs.
According to La Repubblica, Spanish giants Real Madrid may come knocking on the door should Jose Mourinho leave the Bernabeu, with Petkovic being highlighted as Dortmund's preferred target.
The Bosnian only took over at the Stadio Olimpico last summer and has taken the Aquile to the Coppa Italia final, as well as third in Serie A.
