Ranking the 5 most iconic games of Pep Guardiola's managerial career

#3 Bayern Munich 5-1 Borussia Dortmund | Bundesliga, October 2015

FC Bayern Muenchen v Borussia Dortmund - Bundesliga

Guardiola's Bayern expedition was one of great tactical experimentation and domestic dominance. He took an already excellent side to re-engineered heights of modern attacking football, albeit he will always be criticized for failing to bring back the Champions League to Germany.

Guardiola fit in Robert Lewandowski and Thomas Muller to devastating effect against arch-rivals Borussia Dortmund, as Thomas Tuchel was humiliated in his first Der Klassiker.

The 5-1 victory on the night signified the vast difference in class, quality and technique between the two sides as Bayern once again romped to the title.

#2 Barcelona 5-0 Real Madrid | La Liga, November 2010

Barcelona v Real Madrid - La Liga

The 5-0 drubbing of Real Madrid, led by philosophical rival Jose Mourinho, was an emphatic statement of dominance and superiority.

Guardiola's Barcelona displayed a sleek style of football with the midfield brilliance of Iniesta and Xavi, and the attacking excellence of Lionel Messi and David Villa.

Many thought Jose Mourinho was the chink in Guardiola's armor and the kryptonite of superhuman football.

Setting up in a low defensive block, Barcelona dominated the game and pressurized Madrid into making mistakes, leading to goals from Xavi, Pedro, Jefferen and a double from David Villa.

#1 Barcelona 1-1 Chelsea | UEFA Champions League Semi-Finals, 2008-09

Victor Valdes celebrates a goal for Barcelona

Barcelona's victory over Chelsea in the Champions League semi-final was one of the most thrilling and tightest of finishes that not even Guardiola could have claimed to have masterminded. The match was a combination of fate, luck and tactical mastery.

The second leg at Stamford Bridge had everything to play for as a goalless first leg at Camp Nou meant the winner would take it all on the night.

A star-studded Chelsea with the likes of Michael Ballack, Michael Essien, Didier Drogba and Frank Lampard, were a premier force looking for their first-ever Champions League crown.

A Michael Essien scorcher gave Chelsea the lead under 10 minutes, with Barcelona throwing it all at their opponents with impeccable ball retention and pressure.

With a red card given to Eric Abidal, all hope seemed lost for Guardiola's Barcelona as Chelsea's resilient defense would not budge an inch.

That was until Messi found Iniesta on the edge of the box, who proceeded to launch a screamer into the top corner to send them through on away goals.

The game has gone down in infamy because of the controversial standard of refereeing, with Chelsea denied over three valid penalty shouts.

However, the resilience and spirit shown by Guardiola's Barcelona shone bright at the death and powered them on to their first Champions League under his reign.
