Toure looked likely to start behind Aguero, until the injury to Delph
The injury to new signing Fabian Delph looks to have scuppered any plans Pellegrini may have had to playing Toure behind Aguero from the off. Toward the back end of last season the Chilean had finally come to terms with the fact Toure isn’t the defensive centre mid he once was, but still played a pivotal role in everything they did going forward. He started playing the big Ivorian off Aguero and it yielded results, but the injury to Delph means City only have two central midfielders in Fernando and Fernandinho in the first team squad. This will likely, atleast for the start of the season, force Pellegrini into playing Silva centrally of Aguero as opposed to the wing, and giving either Navas or Nasri a chance to impress from the right.
Sterling and Silva already look to have struck up a partnership
The big question mark behind Sterling’s signing was whether he would gel with City's top attacking talent, and he’s gotten off to a good start. The two interchanged care-free in the preseason games they were involved in and with Sterling’s speed and Silva’s vision, the two along with Aguero will strike fear in to any defence they come up against.
Sterling is operating from the left
In the games he featured in after his British record signing, Sterling looked to be operating from the left and cutting in on his right. This may be a feature of City’s play next year however should Toure eventually move behind Aguero, it’ll be between himself and Silva who plays on the left and who plays on the right.
Ilheanacho looks a prospect but needs game time to develop
Ilheanacho had a good preseason last year before committing to City, now he’s had an even better one and with Jovetic (and potentially Dzeko) on their way out of Manchester, the youngster may get his chance. Pellegrini will have to have a lot of faith in the youngster to make him the 3rd choice striker, particularly with Bony and Aguero’s injury record of late. Of course another option for the boss is to replace Aguero/Bony should they get injured with Nasri or Navas and play Sterling through the middle.
