City demand cash for Tevez
Roberto Mancini has raised the prospect of Milan securing Carlos Tevez's services next month and delaying payment until the summer, provided they guarantee to buy him.
However, Premier League leaders Manchester City later moved to reaffirm their position that the Argentinian would not be released without money up front.
Mancini added: "I had a good relationship with Carlos and what's happened is really strange and frustrating for me.
"I have good behaviour with him and I don't know what's happened to cause this."
He added: "I hope we can find a solution. With Carlos in the squad, we were a better team, for sure."
