Arsenal are now seven points clear of City and have the destiny of the title in their hands as they chase their first English crown since 2004
City have a game in hand on the Gunners, who visit the Etihad in April but Guardiola will rue another game in which his side lost control in the second half.
Not for the first time this season, City slipped up in the second half, taking the total number of points dropped from winning positions this season to 13.
But Guardiola is adamant City can still overhaul Arsenal in their last nine games.
"Still many games to play, them (Arsenal) one less," Guardiola said.
"There are games where we don't deserve it. Today we played in general good for 90 minutes.
"It's not about this action or that action. In general, when we analyse the game, the game was well played."
