A late Gabriel Jesus goal secured City a 1-0 victory over Southampton on Sunday and with it, broke the 100-point barrier in the Premier League for the first time in the division's history.
It topped off an incredible record-breaking season for the 'Sky Blues' but Guardiola still believes there is room for improvement.
He told reporters after the win: "A team is individual players and always you can improve individual players, so with that it makes sense to go to the training sessions and do it.
"When you analyse the numbers, I would say we can't improve the numbers, no. We cannot be better in terms of numbers.
"In terms of playing football, yes. Because the players can do better, the manager as well, in a group, in a team we can do better.'
