Guardiola's ascent from Barcelona B Head Coach to UEFA Champions League winner took place against a footballing backdrop very different to the one we find now in 2016.
Following an era where the moment of transition between defence and attack had been pinpointed as the single most decisive action in a match, allowing pragmatic, counter-attacking football to prosper, Guardiola showed that there was another way.
He won the La Liga title in three of his four seasons at the Camp Nou and lifted the UEFA Champions League twice.
In addition, the Catalan giants won the Supercopa de Espana three times, as well as twice lifting the Copa del Rey, the UEFA Super Cup and the FIFA Club World Cup.
There were eyebrows raised when he decided to take over at Bayern Munich in 2013, particularly as they had just won the Champions League and domestic treble.
Could Pep do it without Messi? Without Iniesta, Xavi and Busquets? Without his mother tongue? In another culture? In another league? How do you take over a treble-winning Bayern Munich side at the peak of its powers?
