Expectations were sky-high when Guardiola alighted in Manchester after years of being courted by City, but a title challenge failed to materialise and his side did not make a mark in any of the cup competitions.
"We decided last season we could change the team to make the team younger for the next four or five years".
With Ibrahimovic and Wayne Rooney no longer around, there is pressure on Paul Pogba to establish himself as the team's leader after blowing hot and cold in his first season following his return from Juventus.
Back-up goalkeeper Willy Caballero, full-backs Pablo Zabaleta, Bacary Sagna and Gael Clichy and wingers Jesus Navas and Nolito have all left, while the unwanted Joe Hart has gone out on loan again to West Ham United.
The 35-year-old was the only United player to get into double figures in the league.
"We are in a position to do quality work better than we did in the first season, so I am convinced that our second season, in terms of the quality of our team, is going to be better". The 24 names that featured for the Blues included the exiled Costa and departing Loic Remy, as well as academy youngsters Andreas Christensen, Charly Musonda Jr., Jeremie Boga and Fikayo Tomori, who can list one Premier League appearance between them.
Perhaps the most enticing question is over how he will use his attack, and whether he will let Romelu Lukaku and Rashford wreak havoc together up front, and whether he will play more of his more creative attackers - like Anthony Martial and Henrikh Mkhitaryan - behind them rather than always having more of a worker like Jesse Lingard.
Leicester famously defied odds of 5000/1 from the beginning of 2015-16 to win the Premier League that season, and bookmaker Marathonbet is offering the same on Brighton claiming the trophy this time around.
In an era before innovative social media signing announcements, clubs were still attaining coverage in unique ways, and prior to that inaugural Premier League season the Blades were thrown a Christmas party by boss Dave "Harry" Bassett.
"We had lots of dominance at home, lots of chances, lots when the match should be two or three nil and in the end was 1-1". Third-place City finished 15 points behind champions Chelsea, with Tottenham Hotspur in second place. Ederson made 27 appearances in the Portuguese League and only conceded 12 goals. And their arrival has filled Mourinho with belief they can go all the way this time and continue his fantastic run.
Empowered by a close-season transfer splurge of some £200 million ($264.8 million, 233.5 million euros), Manchester City are the early favourites to topple Premier League champions Chelsea. That wasn't enough last year and it won't be enough this year.
