Under the deeply divisive figure of Roberto Mancini, Manchester City endured a torrid time in the Champions League.
Having been placed in two exceedingly tough groups, the experienced Italian was unable to guide the Premier League title hopefuls past the first round in consecutive seasons. This, added to the toxic dressing room atmosphere that is believed to have developed during the previous campaign, is believed to be among the main reasons for his departure during the summer.
Mancini's replacement, Manuel Pellegrini, enjoys a strong reputation in club football's most-prestigious tournament. Having guided unfancied La Liga duo Villarreal and Malaga into the latter stages, City fans will be desperately hoping he possesses the skill to turn their club into a formidable and genuine force on the continent.
Following an emphatic away win over minnows Viktoria Plzen in their opening group game, City's next Group D assignment should prove far tougher as they welcome defending champions Bayern Munich to the Etihad Stadium.
Here, GMS lists five key individual battles that could take place at the Etihad on Wednesday evening. Obviously such contests are subject to the respective lineups we predict each manager to choose, so they could be subject to change.
