Pep Guardiola created some life-long friendships during his four-year spell in charge of Barcelona and was highly regarded by most of the players at the Camp Nou - with the exception of Zlatan Ibrahimovic. And when the Spaniard's Manchester City side drew the Catalan giants in the Champions League this season, it was bound to get both the players and fans talking.
One of the City boss' former players, Andres Iniesta, was a vital part of a highly successful Barcelona side that won 15 major trophies in just four years, including three La Liga titles, three Super Cups, two Copa del Rey's, two Club World Cups and the Champions League twice.
And the 32-year-old is confident that Guardiola will be able to recreate the same success he has had at Barcelona, and most recently at Bayern Munich in the Bundesliga, with City over the coming seasons

But with the Champions League presenting the City boss with the opportunity to return to Barcelona, where his managerial career began with Barcelona B, the midfielder believes the Premier League outfit will put up a major fight in the competition this season, and could have a big say in stopping the European crown heading to the Camp Nou.
As reported by the Manchester Evening News, Iniesta said: "What Pep has done for the club (Barcelona) will always be remembered, but he is the coach of Manchester City now - and I believe with their quality and Pep's leadership they will be a club that will be challenging for the Champions League this season."
Like Iniesta, Manchester City fans are expecting Guardiola to have a big influence on their success in the Champions League this season, with the club having reached the semi-finals for the first team last campaign.
The club haven't had the best of success in Europe's elite club competition, and the beginning of their Champions League campaign was delayed on Tuesday evening when torrential rain saw their opening group stage fixture against Borussia Monchengladbach postponed.
But while Barcelona emphatically began their European campaign with a 7-0 humiliation of Celtic, Iniesta insists the club are not overlooking the group stages, in which they'll be expected to come out on top, and Guardiola's return on October 19 is not being discussed.
"When the group was drawn it was inevitable that much would be made about Pep returning to Barcelona again - but that is not what this group is about,” Iniesta added.
"It is a group with four very strong teams - and it would be disrespectful to make it all about Pep and Barcelona.
"For the players we are not even thinking about Pep's return, we are focused on Celtic. They are playing some good attacking football, they have a new coach, and from experience we know they always play with spirit."
