In possession, City's preferred starting XI looks like this [BBC]Our tactical correspondent Umir Irfan has dived in to what Guardiola is doing at City. Here is one of the areas he has uncovered. Attacking midfielders at full-back workWhen Guardiola reinvents his system, changes are made based on the players he has rather than a predetermined idea of what system he wants to play. City have options at full-back this year - Nathan Ake offers a pure defensive profile, as he did in City's Treble-winning season, while Rayan Ait-Nouri and Rico Lewis give City positional versatility and attacking quality in small spaces.

Matheus Nunes assisted Erling Haaland's goal against Liverpool this season - note Nico O'Reilly's central position with Jeremy Doku positioned wider on the edge of the box. [BBC]Their physical profile helps them dominate defensive duels as well as get back to defend counter-attacks too. It also allows them to push high up the pitch, acting as attackers, usually in one of two ways. Both full-backs can play wide, which frees City's wingers to move centrally, a tactic that has been very successful this season. On the ball, they can play crosses from these positions on their stronger foot too. Alternatively, when wingers take a wider position, both full-backs have the ability to underlap the wingers, getting into dangerous areas centrally.

O'Reilly scored against Bournemouth after surging into a central shooting position. Nunes is slightly wider, with Cherki moving into the box.
