As Chelsea visit Eastlands on Saturday, the environment will be heated up as things had got ugly last season when the two teams met.
When Chelsea last faced City in Stamford Bridge earlier this year, the Terry scandal was at its peak and to add further insult the Blues' were defeated 4-2 by Mancini's men. Chelsea however, went on to win the Premier League while the high spending Manchester City missed the Champions League bus and had to be content with an Europa League spot.
Hence, on Saturday when Chelsea faces Mancini's team of multi-million dollar players it will be a battle of vengeance and supremacy. While City has spent millions this summer to sign top quality players, the team is yet to gel and though the players may be brilliant individually, they are not that good together as has been proved in their latest defeats.
On the other hand, Chelsea have a team that seems to be in their peak from and the understanding among the players cannot be better than this. They are presently the most-feared team in the Premier League given their clean record as well as goal-scoring prowess.
Hence, the City of Manchester stadium will face a heated duel among to rich clubs of the Premier League and while City will be looking to register their earlier feats, Chelsea will be on the look-out for revenge and maintaining their so-far clean record intact.
In the following slides, we will take a look into the five key duels that will define the this weekend's most-awaited match as Carlo Ancelotti's ageing boys take on his fellow-countryman's star-studded team.
