Pep Guardiola maintained that Manchester City have to complete a perfect run-in if they are to hold off Liverpool in the pulsating title race.
The defending Premier League champions overcame Brighton with three second-half goals from Riyad Mahrez, Phil Foden and Bernardo Silva.
The Etihad Stadium was nervous before Mahrez's breakthrough but City went one point clear of Liverpool with six games remaining.
'There are six games left and if we win all the games, we are champions,' Guardiola said.
