While Mancini believes that United are worthy table toppers, the Italian doesn't think that the Red Devils deserve to be leading by such a big margin.
"We do not deserve to be 15 points behind Manchester United," Mancini said in a press conference. "They play very well and have won a lot of games and they deserved to stay on top but not by 15 points.
"The table is not true. Now we have eight games and if we win a lot of those games maybe we can close that gap."
City will go up against their rivals at Old Trafford on Monday evening.
