Man City have one player who could help unlock dream partnership

When you have an excess of central defenders, one way to keep them all happy is to play an extra one. That's exactly what Pep Guardiola did as Manchester City cruised past Al Ain in the Club World Cup, and it was a system made possible by one of the June arrivals.

That meant Nico Gonzalez, Ilkay Gundogan, Bernardo Silva and Claudio Echeverri could play inside and dominate midfield.
