Lucien Favre held nothing back when assessing Borussia Dortmund's performance after a humiliating 5-1 home loss to Stuttgart.
The stunning result means Dortmund have now suffered three straight defeats at home in the Bundesliga for the first time since the 2013-14 season, when Jurgen Klopp was in charge.
Favre's future will come under scrutiny following this latest setback, despite steering BVB through to the last-16 stage of the Champions League.
