Jose Mourinho is being linked with Lucien Favre's job at Borussia Dortmund.
While Favre is currently safe, doubts are emerging about the Swiss inside BVB this season.
And BILD says former Manchester United manager Mourinho has been discussed as a replacement.
Mourinho is close to BVB chief Hans-Joachim Watzke and they're in contact regularly.
This year, the Portuguese stated: "I think the Bundesliga is really interesting.
"I admire the work of BVB and its attempt to compete with a giant like Bayern."
