Guardiola had a shaky start to life in England as the Citizens finished 15 points below champions Chelsea in his first season.
Manchester City were pushed all the way in the title race by Jurgen Klopp's Liverpool last term but a sublime 14-game winning streak saw them end the season as champions for a second straight campaign.
Last season, Manchester City had to wait till the last day of the season before winning the Premier League title, beating Liverpool with just one point on the final standings.
But speaking in Catalonia, Manchester City boss Guardiola appeared to question whether or not Neymar could repeat those successes if he went back.More news: Sea rescue should not be criminalized: German gov't

Pep Guardiola believes that the Anfield atmosphere is the best ever since he has experienced as both manager and player.

That is why I've had it, since managing the [Barcelona] B team, as the absolute priority.
"I'm trying to be a good coach - that hasn't gone too badly in this decade".
Asked about potentially returning to the club as manager, Guardiola insisted he has no reason to leave the Citizens, due to the league in which they plan and their flawless facilities, but also hinted that he does not like the way Barca is run.More news: Yasiel Puig erupts after being hit by Chicago's Pedro Strop
"With Silva, Bernardo Silva, Sterling or Aguero, all of them less than one metre 20!" We don't let in many goals and we dominate in possession. We have the same ideas that we had when we trained the Barca youth team in the third division.
He said: "What I like more is that I have proved that people who said we can't play the same way in Germany or in the Premier League were wrong".
Neymar moved to Paris to get out of Lionel Messi's shadow at the Nou Camp but hasn't quite lived up to his world-record £198million price-tag and has had his problems away from the pitch. I won't go back here [to Barcelona] or Germany.More news: Tim Cook slams alleged rift with Jony Ive as ‘absurd’
