Those additions have helped to restore domestic dominance, on the back of a Premier League and Carabao Cup double in 2017-18, and Guardiola feels his squad now requires mere minor tweaking.
It didn't quite match the drama of Sergio Aguero's now fabled last gasp victor on the final day of the season six years ago, but Gabriel Jesus' victor against Southampton on Sunday put the finishing touches on Manchester City's remarkable Premier League season.
Guardiola said: "Now is the time to enjoy what we've done this season".
A big summer now arrives for the Saints with a permanent managerial appointment, player outgoings and signings all sure to be witnessed before August.
"It's a good club, I'm a professional football manager, I would love the opportunity".
"I think what will remain is the formidable human aspect of the last 22 years - that is special and I will cherish that".
Additionally they received the Carabao Cup and on Tuesday Guardiola outlined his summer season spending plans, claiming he desires exclusively a alternative for the departing Yaya Toure and maybe one other ahead.More news: Veteran Advocacy Group Seeks Support For McCain in Rejection of Haspel
Manchester City goalkeeper Ederson has signed a two-year contract extension, committing him to the Premier League champions for the next seven seasons. However, he showed another side in the final 15 minutes as both Brahim Diaz and Phil Foden were brought on - giving each player a fifth appearance of the season to earn a Premier League winners' medal. They scored the most points (100), most goals (106), recorded the most wins (32), and won the league by the biggest margin (19 points).
"I don't usually win awards because it's the fellow managers who vote for it", Guardiola added.
Manchester City reach 100 points!
Guardiola feels his team have been rewarded for their playing style and doubts their record exploits will be matched anytime soon.
"I looked at the squad and thought they need maybe a little bit of direction, they've lost confidence; still the risk, from my point of view, in terms of representational damage, if it went wrong.
You are a top human being, I will be in your debt forever so thank you very much", he said.
