Manchester City manager Roberto Mancini is refusing to be drawn into a war of words with Bayern Munich chairman Karl-Heinz Rumennigge, despite the continued criticism of the club's financial dealings.
City's transfer policy could eventually mean they could face penalties for breaching UEFA financial fair play regulations.
But instead of allowing the governing body to deal with the situation as they see fit, Rummenigge has seemingly done all he can to draw attention to City's financial dealings.
"I don't understand Rummenigge's behaviour against Manchester City," Mancini said.
"This has been six months now that he talks against us. He says he hopes Napoli get through to the second stage [instead of City]. I don't understand what has happened with Rummenigge, and tomorrow I want to ask him.
"I just don't understand why, every time, an important man like Rummenigge, representing one of the top clubs, says things against us," Mancini added.
"There are other teams in Europe that have problems with financial fair play, not just Manchester City. Rummenigge knows his football – he was an incredible player – but I just don't understand why. I don't know what his problem is."
On the pitch, Mancini requires several favours tonight if his City side are to progress to the next stage of the Champions League, not least from Bayern themselves.
His side have to beat the Bundesliga outfit and hope that second placed Napoli slip up against group whipping boys Villarreal.
