Italian Mancini, who arrived at the Etihad Stadium back in 2009 to replace Mark Hughes, and brought the Premier League title to the club in 2012 when Sergio Aguero's last-gasp winner against QPR sealed a the most dramatic end to the season in recent times.
But the relationship between the former Inter manager and the City hierarchy became more and more uneasy as time went on, and was unsurprisingly sacked as the 2012-13 season drew to a close, with Malaga boss Manuel Pellegrini taking over in his place.
The 49-year-old wasn't out of work for long though, taking over as Galatasaray manager in September. Having come through a tough Champions League group with Real Madrid, Juventus and FC Copenhagen, Mancini's men were paired up with Chelsea in the knockout stages - only to lose 3-1 on aggregate against Jose Mourinho's side.
Mancini saw Mourinho's men in action over two legs, but when asked who he thought would win the Premier League, he said that his former side, Manchester City, should win the league as they simply have better players than their competitors, and also disregarded Liverpool's title challenge.
"I think that Manchester City's the best team," he said. "They have the best players. I don't know if Liverpool, also doing very well in this moment, can win. I think it will be a fight till the end between City and Chelsea."
City sit just six points behind first placed Chelsea but have three games in hand leaving the title race firmly in their hands. Mancini's comments certainly appear to be a tactic to put more pressure on his replacement Pellegrini, as Mancini has regularly said that he should take most of the credit for their success this season.
