Former Bayern Munich II coach Mehmet Scholl has revealed that the Bundesliga champions were ready to sell Jerome Boateng in the summer transfer window following his relatively disappointing performances in 2012-13.
The 25-year-old defender struggled to find his best form last term, but has developed into a key player under new head coach Pep Guardiola this season.
"They held a conversation with Boateng to tell him that he would not be at Bayern much longer if he continued to play like he played last season," Scholl told ARD.
"He has made a big transformation since and you can hardly recognise him any more. When players show a willingness to change and to improve, that shows their class."
Boateng joined Bayern from Manchester City in the summer of 2011 and has since made nearly 100 official appearances for the German champions.
