The 47-year-old, however, insisted that the Premier League remains the top target for the Citizens next season.
City's enigmatic style and substance prompted much debate throughout the season as to how the matched up against other great teams of the Premier League era such as Arsenal's invincibles, Alex Ferguson's United sides and Jose Mourinho's Chelsea.
Ederson, for example, was ideal, but then at the end you are saying "go and try the Premier League and try to play" and you don't know if it's going to happen.
That heavy investment paid off with City winning the Premier League and League Cup, but Guardiola said fans should not expect similar spending.
Pep Guardiola has said Manchester City's celebrations of their stoppage-time victory over Southampton last Sunday were wild because reaching 100 points was such an important goal for his team.
"It gives you the consistency to arrive at the right moment, the Champions League is so complicated the opponents are so good, all of them".
Guardiola has previously won the Champions League with Barcelona in both 2009 and 2011 but has not reached the final since.
18 of those wins came successively, in a run spanning from August until the end of December, another record taken from the previous champions.
"That competition, you play at Anfield, Barcelona, Real Madrid, Roma, Bayern, United, Juventus, all of the big clubs".
Espirito Santo won Championship manager of the year, while Shrewsbury's Paul Hurst took the League One prize and Coleman won the League Two award.
