It seems as though finally, after more than 1000 days in charge of Real Madrid, Jose Mourinho has achieved his mission of derailing Barcelona. Too bad he's probably on way out of the Bernanbeu in the summer.
While the story goes that Mourinho will move on in the summer after an argument or five too many with his players, board members and pretty much everyone else he can now leave knowing he has fully got the better of Barcelona.
Madrid's 3-1 win over their rivals at the Camp Nou was almost perfect. Sensing their rivals' vulnerability, Los Blancos pounced and exploited their flaws, sweeping a side who had been their superiors for much of the last five years.
It will have been a sweet moment for Mourinho as his side earned a place in the Copa de Rey final and landed a huge blow to Barcelona's ailing aura - but does it count as his best ever day, or night, at the office? Check out the Special One's greatest ever matches.
Barcelona 1-0 Inter Milan, Camp Nou 2010
It's little wonder they're not exactly huge fans of Mourinho's in Catalonia, is it? Long before he was prowling the touch-line at the Bernabeu and eyeing up Tito Vilanova's eye as the perfect place to rest his thumb, Mourinho was causing mischief while in charge of Inter Milan.
The Portuguese coach had guided his side to a 3-1 advantage in the first leg of their Champions League semi-final against Barcelona in 2010 at the San Siro, but most thought Pep Guardiola's side would make up the deficit in the return leg on home soil.
Inter's task looked even more daunting after Thiago Motta was sent off with just 28 minutes played, but the Italians side clung on to a 1-0 defeat to secure their place in the final. Mourinho was in his element as the villain upsetting a Barca team at their very peak.
