Much of the focus has been on the new fullbacks, Kyle Walker and Benjamin Mendy, as well as the new goalkeeper, Ederson Moraes, who stands behind City's only potentially weak area - centre-back, where Guardiola is still looking for reinforcements to buttress John Stones, Nicolas Otamendi and Vincent Kompany, a great Premier League defender who is unlikely to suddenly become sound in body.
But the overwhelming strength of City's orchestra is in midfield, where the range of talents looks irresistible. If all are available, Guardiola will somehow have to choose from Fernandinho, Yaya Toure, David Silva, Kevin De Bruyne, Bernardo Silva, Leroy Sane, Raheem Sterling and Ilkay Gundogan, who is fit again. Even allowing for the strength of Real Madrid and Barcelona, City's midfield talent pool is arguably the deepest in Europe, with Bernardo Silva adding more width to the wing play of Sterling and Sane, as well as yet more ingenuity in the No10 area.
With Sergio Aguero and Gabriel Jesus as strikers, the torment for opposition defences will be unrelenting, provided City's attitude is right.
In the mega-money age, their pattern has been to win the league, then drop away, or display complacency against the smaller clubs. Brilliant, in phases, City have yet to become the dominating force in English football. Chelsea have been more resilient in that respect. But Guardiola's cull (Nolito and Jesus Navas were others who fell below the required level), and his upgrading of the defence (Danilo is another, versatile acquisition) explain why bookmakers make City clear favourites at 15-8 to take the trophy off Antonio Conte's team.
The Guardiola-Jose Mourinho rivalry was built up frantically this time last year. In the event neither club could reach the top two places, with London in control, in the shape of Chelsea and Spurs, who have been chastised by Danny Rose, their left-back, for the size of their pay packets, and whose move to Wembley deprives them of the powerful White Hart Lane ingredient. In May, Spurs finished with 86 points, were unbeaten at home (17 wins, two draws) and scored the most goals, with the fewest conceded. Without reinforcements, however, and with Wembley feeling like a showpiece ground rather than a cauldron, 9-1 seems a fair assessment of their chance of moving up to the gold medal position.
Mourinho's first season was more successful than that of Guardiola, in that United won the League Cup and the Europa League, thus returning to Champions League action without having to chase Chelsea and Spurs at home with a squad unbalanced over three seasons of erratic purchasing.
All the evidence suggests Mourinho was aghast at the poor quality of his squad, but has rectified that, in part, by adding strength along the spine, from Victor Lindelof (centre-back), Nemanja Matic (defensive midfield) and Romelu Lukaku (striker). The worst league season of Mourinho's managerial career will have to sprout wings to become a title-winning campaign in his second season at United, but they will be stronger, especially if Paul Pogba progresses - even if Mourinho's tactical, slower style of play is less appealing than the speed of Liverpool, the creativity of City and the formidable Harry Kane-Dele Alli combination at Spurs.
As for Arsenal, the best policy is to expect more of the same until there is hard evidence that the ship has finally come in. Alexandre Lacazette's arrival from Lyon is an upgrade on Olivier Giroud, Danny Welbeck and Lucas Perez, but no judgment can be made until we know whether Arsene Wenger has managed to hold on to Alexis Sanchez. The same could be said of Liverpool and Philippe Coutinho, their most inventive attacking player, and most likely game-changer. Barcelona's pursuit of Coutinho stems from the loss of Neymar, and the Premier League has a poor record of stopping world-class players gravitating to Spain's two biggest clubs.
Below the top-six cosmos, all sorts of interesting themes unfurl, from promotions for Brighton and Huddersfield to Rafa Benitez's return with Newcastle, Everton's emergence as a big spender and West Ham's second attempt to settle at the current home of the World Athletics Championships.
Leicester City plunged from champions to 12th, and are at a T-junction now.
The title-holders, Chelsea, also have an uncertain feel to them, despite making three good signings in Alvaro Morata, Antonio Rudiger and Tiemoue Bakayoko.
Internal politics, and Conte's restlessness, appear to be Chelsea's only real hazards. If they falter, or fall out, Manchester is ready to capitalise, with City's grand design around Guardiola ready for completion.
