Claudio Bravo (Manchester City):
Having moved to Manchester City from Barcelona in the summer transfer window under Pep Guardiola, the Chilean international, who was fresh from a victory at the Copa America, was expected to help City mount a title challenge with strong performances at the back but Bravo has been anything but solid so far this season. He has shown a peculiar weakness in the air that was not tested in the La Liga while his concentration levels and passing accuracy have also gone down considerably. The Premier League can do that to people but with City fighting for the title, Bravo remains the weakest link in the side for Guardiola this season.
