Pep Guardiola has warned his Manchester City players that complacency is the biggest threat to their push for domestic and European domination. Guardiola's unbeaten Premier League leaders visit Chelsea on Saturday sitting two points clear of closest challengers Liverpool.

City are well on course to defend the title they won with 100 points in May and are also through to the Last 16 of the Champions League with a game to spare. They have managed all of that largely without the services of last season's club player of the year Kevin De Bruyne.
