Jose Mourinho's managerial career really did peak in 2010.
Despite enormous success with FC Porto and Chelsea, the Portuguese manager went one better with his Inter Milan side and won an unprecedented treble.
Inter secured Champions League glory by comfortably defeating Bayern Munich 2-0 in the final.
But the sternest examination of their credentials came in the semi-final round against Pep Guardiola's awesome Barcelona side.
In the first-leg, Mourinho's team bounced back from a goal down to win 3-1 in the San Siro. Wesley Sneijder was simply unplayable that night.
But many still favoured Barcelona to progress given that the second-leg was was in the Camp Nou, a stadium that represents a daunting prospect for any team.
Inter were even reduced to 10-men in Catalonia when Sergio Busquets pathetically fell to the floor to get Thiago Motta sent off, but that only enhanced the defensive masterclass that Mourinho delivered.
A stunning strike from Gerard Pique late in the second-half was not enough as Inter's rearguard held out and the scenes at full-time are the stuff of legend.
Mourinho charged onto the Camp Nou pitch like a maniac with his hand held aloft, taunting the fans he once called his own when he worked as Sir Bobby Robson's translator.
You can relive both legs of that memorable semi-final below, but we won't blame you for simply scrolling to the end to watch Mourinho's celebration - one that Victor Valdes tried and failed to bring an end too.
How was it been 10 years since that iconic Champions League evening under the Spanish night sky?
Due to Mourinho going 'full Mourinho', Pique's wonder-goal has really slipped under the radar over the past decade.
The towering defender turned into Lionel Messi for a brief moment with his gymnast-like swivel, proving once again that he is one of the greatest ball-playing centre-backs of all-time.
But Pique's efforts will forever be on the undercard, because the Mourinho main event - which Inter still call 'the most beautiful defeat' - is what will be remembered and spoken about in the decades to come.
