Bayern Munich chairman Karl-Heinz Rummenigge has hit out at Manchester City sporting director Txiki Begiristain following his recent comments that they could sign players from the Bundesliga champions.
The Citizens have been linked with a number of Bayern stars since it was announced Pep Guardiola will swap the Allianz Arena for the Eithad Stadium in the summer.
And speculation has intensified after Begiristain refused to rule out the possibility of City launching bids for Bayern players once the season comes to a close.
However, Rummenigge has warned City that Bayern have no intention of selling anyone them and says they should show more respect.
"I was quite surprised about my Manchester City colleague's comments," Rummenigge was quoted as saying by Bild.

"Contracts are contracts and they should be respected, also by Manchester City."
City were credited with an interest in David Alaba but the Austria international ended talk about his future by signing a new deal with Bayern until June 2021, much to the delight of Rummenigge.
"Bayern Munich always want to be the team in charge. That is always our goal," he added.
"We also managed to achieve that in the case of Alaba. Bayern were the club calling the shots. And not some club from England with the crazy offers they can make."
