#2 Pep Guardiola - FC Barcelona
Magical, mesmerizing, unreal.
This is exactly how each and every football fan describes Guardiola's time as Barcelona's boss till date. In May 2008, Guardiola was appointed manager of the senior Barcelona squad to replace Frank Rijkaard at the end of the 2007-08 season.
He made a huge call by not keeping Ronaldinho, Deco and Samuel Eto'o as part of his plans. That sparked the start of a new era at the club, as their brand of football was simply flawless.
Guardiola's men destroyed Real Madrid 6-2 at the Bernabeu on their road to the Spanish title. They then completed a treble win as they defeated Manchester United 2-0 in the Champions League final, with the Copa del Rey title being more or less a formality for them.
Pep finished the calendar year 2009 with six trophies, becoming the only manager in history to do so. He was also the youngest one to coach a Champions League winning team.
2009-10 was relatively dull for him in terms of silverware as he only lifted the La Liga trophy. But in the following season, the team went on to clinch a second Champions League title in three years by defeating Manchester United yet again.
In May 2011, Barcelona won the Spanish top flight title - the club's third in a row. But the 2011-12 season saw Guardiola face much criticism for his tactics as Barcelona missed out on the Champions League and La Liga.
However, he won the Copa del Rey as his final and 14th trophy as Barca manager, making him the most successful manager in the club's history.
On 27 April 2012, Guardiola announced he would step down as Barcelona's coach at the end of the season. Those four years will never be forgotten by the Catalans.
