Pep Guardiola is lauded as one of the most successful, revolutionary and charismatic managers of our time.
His unique ideas and tactics have caught the eye everywhere the Spaniard has been and were even on show in his first Premier League game as Manchester City manager.
The way full-backs Gael Clichy and Bacary Sagna were used in midfield whenever they had the ball sent analysts and pundits alike into overdrive trying to figure out what it would accomplish.

Hours and hours of work on the training ground always ensures a Guardiola team is well-drilled, organised and most importantly very difficult to beat.
However, it isn't always clear exactly what it's like to work under such an obsessive and demanding character.

Thierry Henry has shed some light on some of Guardiola's methods - which don't always rub off on everyone - during the time he spent in Barcelona between 2007-2010.
In an interview with The Football Republic, Henry gave an honest assessment of the new Man City boss from a player's perspective and revealed it isn't quite as rosy as it is perceived to be.
"[He is] intense. He wants to dominate. He wants to control everything. He wants to know everything. He wants to be in charge of everything," Henry said.
"It's just intense. You have to be ready to cope with that.
"It's not an easy thing to do. He said it himself: after two or three years he doesn't stay too long at a club because of the intensity that he has, he's not an easy one to deal with. But he has been successful everywhere he went."
Guardiola does tend to generate a solid relationship with his players but there is little doubt his 'intense' style requires a period of adjustment, particularly if his predecessor was the more laid back Manuel Pellegrini.
He has also earned somewhat of a reputation for his ruthless nature, as proven by the decision to pick Willy Caballero over Joe Hart in goal for City's opener against Sunderland.
It is very difficult to argue with Guardiola's record, six domestic titles in Spain and Germany accompanied with a pair of Champions League victories he picked up at Barcelona. His methods do reap rewards.
Meanwhile, Henry has played down his former side's chances of winning the Premier League and predicts Guardiola's City to edge the title race.
He added: "I see [Manchester] City winning it but my big hope, as you can imagine, is always Arsenal to win it. I hope finally it can be this year but I think City will edge it.
"Having said that, you have big teams that are not going to play in Europe. That can be an advantage."
