City sit nine points behind leaders Chelsea having played a game more than Mourinho's likely title-winners, but where have Pellegrini's men lost the title?
After winning the most open title race in years in 2013/14, City have again failed to defend their Premier League crown amid a disappointing campaign, and they currently lie in fourth position behind rivals Manchester United.
A record of just eight away wins from 16 games illustrates where City have failed to provide a convincing title defence, and although they have drawn 1-1 twice with leaders Chelsea, they have also lost top-four games with Arsenal (2-0 at home) and Liverpool (2-1 away).
However, it is City's record against mid-table teams that will have concerned Manuel Pellegrini the most. City have lost to Stoke City at home and West Ham United, Burnley and Crystal Palace away, in a mirror image of their last title defence in 2012/13 when defeats on the road cost them dear.
The table below illustrates another glaring problem for City this season, and that is how they have missed the steady flow of goals from Sergio Aguero. The Argentine missed a month of the season over the vital Christmas and New Year period and the stats show how City have failed to replace him or to compensate when he has been off form since then.

City have always been able to rely on their midfield to contribute goals, and once again David Silva (11) and Yaya Toure (8) have chipped in, but although Aguero has scored 17 times this term, fellow striker Edin Dzeko has just four league goals and Stevan Jovetic has five. City have also relied on goals from their defenders at set pieces and in open play in previous seasons, but this campaign has seen just three goals from the back four, who have found themselves over-occupied at the back.
Finding a 20-goal striker to complement Aguero - and ensuring the Argentinean can contribute 20 guaranteed himself - will be top of the list over the summer period.
Another unconvincing Champions League performance appears to have knocked the stuffing out of City, but many fans have cited the injury and loss of form of captain Vincent Kompany as integral to the season's disappointing end. And the summer's re-building process will see a close examination of how the inspirational 28-year-old leader can react to a low-key season in which he and his team have never quite hit the heights.
All in all, it is a period of significant reflection for City's hierarchy as they consider whether Pellegrini is the right man to undertake the re-building process, and also whether key players in recent years, such as Toure, will be with the club next season.
