Former defender Nedum Onuoha says Enzo Fernandez's already established working relationship with Enzo Maresca is proving key at Manchester City. The £125m summer signing from Chelsea has adapted quickly to life at City, helped by being reunited with former Blues boss Maresca. "The fact that Maresca wanted to bring him in from Chelsea means a lot because you can see Fernandez really trusts the coach and the coach really trusts the player," Onuoha told BBC Radio 5 Live's Football Daily podcast.
