The 5-0 hammering of Blackburn Rovers in Wednesday's FA Cup third-round replay took the 2011-12 Premier League champions to 99 goals in all competitions.
Cardiff face a huge task to stem the flow of goals at the Etihad, where the hosts have netted 38 times in 10 league matches, all of which have ended in victory for Pellegrini's charges.
And the visitors' return of six points from 10 away matches will bring them little cause for optimism on Saturday.
However, the Welsh outfit do not have to think back too far to find inspiration ahead of what promises to be arguably their toughest top-flight challenge since earning promotion last season, having beaten this weekend's opponents 3-2 on home soil in August.
That was Cardiff's first Premier League victory, but only three have followed since, with manager Malky Mackay paying the price and Ole Gunnar Solskjaer now in his place.
While the Norwegian's tenure begun with a promising 2-1 FA Cup triumph over Newcastle United, his first league match saw a 2-0 loss to an out-of-form West Ham team last Saturday who climbed above Cardiff and left Solskjaer's side in the bottom three.
The title race is likely to be Pellegrini's top priority and the Chilean has guided his side to six consecutive league triumphs as part of a 10-match unbeaten run in the Premier League.
Squad depth is one of Manchester City's key strengths but they are not without their injury problems.
Solskjaer has very few injury or suspension concerns, but Cardiff's form will have been occupying his thoughts.
Jordon Mutch, the club's joint top scorer on four league goals, has missed the last two games with a hamstring problem, but could come back into the reckoning.
