City's football was, occasionally, dazzling and they were only outscored by champions Chelsea and Tottenham Hotspur, but finding an effective defensive configuration gave Guardiola a constant headache.

John Stones looked shaky following his big-money move from Everton and Guardiola's dissatisfaction with his full-back options saw midfielders Fernandinho and Jesus Navas deployed in the wide defensive positions.

There should not be any shoehorning of players into unfamiliar roles this season after Guardiola signed three top-level full-backs -- Kyle Walker, Benjamin Mendy and Danilo -- at a combined cost of around £124 million.

Guardiola hopes to have put his goalkeeping problems to bed as well, having reacted to Claudio Bravo's travails by bringing in Brazil goalkeeper Ederson from Benfica in a £35 million deal.

Bernardo Silva, meanwhile, arrived from Monaco, further strengthening a stellar attacking department that also contains Sergio Aguero, Gabriel Jesus, Leroy Sane, David Silva, Kevin De Bruyne and Raheem Sterling.

"Manchester City have the best team on paper," ex-England midfielder Owen Hargreaves told the Premier League official website.

"It took a bit of an adjustment for Pep Guardiola, but City are my favourites."

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.

Guardiola has tested out a three-man defence in pre-season, with Stones lining up alongside Nicolas Otamendi and captain Vincent Kompany, whose ability to remain fit will once again be under scrutiny.

Playing three at the back may enable Guardiola to associate Aguero and Jesus in attack, after he generally used a single-striker system last season following Jesus's arrival in January.

Even more so than his old foe Jose Mourinho across town at Manchester United, if Guardiola cannot at the very least orchestrate a sustained title challenge, his gilded reputation will take a sizeable hit.

Last season was the first time in his managerial career that he finished a campaign without having added at least one trophy to his collection.

Another season without silverware will raise serious doubts as to whether he really is the man to carry City to the summit of European football for the first time.
