Mancini admits he is expecting a busy few weeks back at his desk when he returns at the start of next month.
"Many players are linked with City, often for convenience," he told City's website.
"We must be patient, and do the right things at the right time in the market. As a club, we are used to raised prices, but in reality we cannot buy dozens of players so the majority of stories are no more than speculation.
"We know the value of the players we are interested in and will not be forced into paying more than we want to and for obvious reasons I cannot say who are targets are at this stage."
