The Dutchman hard harsh words for the Bundesliga giants earlier this week, but the club's chief feels that the ex-reserve team trainer was in no position to criticise
Jonker sent an e-mail to the Bayern board earlier this week where he criticised their youth academy for lacking of a clear philosophy, among other things, but Rummenigge believes the Dutchman should take a look at himself rather than berate others.
"He should not have written this e-mail. There are situations where you can have a bit of self-criticism. I think we can exclude that in this case," the Bayern director stated to Bild.
Jonker joined Bayern in the summer of 2009 as Louis van Gaal's assistant, and was named caretaker boss in 2010-11 following the latter's departure.
He was in charge of the Bavarians' reserves last term, but left the club this summer for the position of assistant coach at Wolfsburg.
