Pep Guardiola admitted that this season's defence of the Premier League title is his biggest challenge as Manchester City manager.
City last lost two consecutive league games back in 2018 and will attempt to avoid a third against Roberto De Zerbi's Brighton, an opponent Guardiola considers one of the toughest in the division.
The Catalan insists that his players are 'humble' enough to go again after completing an historic Treble but warned they cannot cede further ground on their rivals.
'We have to admit that we have to break it quickly because in the Premier League if you sleep a little bit, take some naps after lunch, then the opponents fly,' Guardiola said.
