One fear is that City are peaking at the wrong time. A bit like Barca a few years ago who were irresistible at this time of the year but couldn't match that level in the later champions league stages. City have genuine competition for places in their squad though, and that might be important. In particular, Bernardo Silva and Aguerro seem surplus. Can Silva and de Bruyne keep this up? And will someone ever challenge their relatively weak central defence?
