Hannes Wolf became the seventh managerial casualty in the Bundesliga this season after being relieved of his duties at VfB Stuttgart on Sunday.
A run of six defeats in seven games has seen the Swabians drop from relative safety in mid-table to relegation candidates.
“We had a very intense and emotional discussion with Hannes following yesterday’s match in which we thoroughly analysed our situation. This discussion brought us to the conclusion that the danger of us not being able to turn our fortunes around under the current management is too great. We need fresh incentives to get back on the right track,” said sporting director Michael Reschke.
