Mills believes that losing to Leeds would get Mancini the sack.
Mancini said that anyone who thought he would be sacked did not understand football.
Danny Mills: "If he thinks every manger in the Premier League has the same remit as him then I'm not sure he understands football.
"I'd be a bit a bit surprised if Tony Pulis at Stoke or Mauricio Pochettino at Southampton had the same remit.
"At a club like Manchester City you're expected to get results.
"Where was Mark Hughes in the table when he was sacked - fourth place?
"His job was to get into the Champions League, it wasn't working, so he got the sack.
"How can one comment of mine make him react like that if he's not under pressure?
"There have been issues too, with Balotelli and Tevez, and it's not been an easy road.
"There was a quote from a City executive about re-looking at the strategy. Well read between the lines of that."
