https://www.youtube.com/watch?v=q7b97sO-hGU 27/10/2009Copa del Rey Round of 32, First Leg, Estadio Santo Domingo. You know Real Madrid, right? The most successful team in European football. Winners of 10 Champions League/European Cup, 32 La Liga, 19 Copa del Rey and 2 UEFA Cup titles. Do you know Alcorcón? When AD Alcorcón (a team from a town within the Madrid Metropolitan Area) was founded in 1971, Real Madrid had already won six European Cup titles. By 2009, when the two teams were drawn against each other in the Round of 32 of the Copa Del Rey, Real Madrid had won three more. By this time, Alcorcón had spent the previous nine seasons in the Segunda B2, a regionalised league which constituted part of the third tier of Spanish football and included Real Madrid's reserve team, 'Real Madrid Castilla'. The chance to play their more illustrious neighbours was huge for the club. Los Alfareros had never played a team from La Liga before, even in cup competition and just being on the same field as Real Madrid would be the greatest moment in the club's history. By the time the teamsheets were given out the gulf in class was obvious. Madrid did not have their first XI on the field (one notable absentee being the injured Cristiano Ronaldo), but taking the field at Estadio Santo Domingo that day was a side which included Raúl, Karim Benzema, Guti and lvaro Arbeloa. Alcorcón on the other hand had a forward line led by future Kilmarnock striker Borja Pérez, who was joined up front by Diego Cascón, a new signing who had scored 5 goals in 29 games in Segunda B for now defunct Polideportivo Ejido the previous season. This game was a mismatch by anyones estimations and as the teams came out in front of a full crowd of 3,000 at the Estadio Santo Domingo, few would have expected what followed. It was not that Real Madrid lost that was the real surprise, it was how they lost. In a match which Alcorcón dominated, some would be surprised they did not win by more. In the 16th minute Borja Pérez curled a shot from the edge of the area which beat Jerzy Dudek's outstretched arm. Six minutes later a pass across the goal was turned in by Spain international Arbeloa as an own goal. By the 39th minute Alcorcón were 3-0 up against the mighty Real Madrid after Ernesto's well placed finish. After half time another Borja Pérez goal put the result beyond doubt. In their first ever Round of 32 game, Alcornón had beaten Real Madrid 4-0. In the second leg, Real Madrid managed a 1-0 victory which put Alcornón through 4-1 on aggregate. The defeat of Madrid, dubbed 'Alcorconazo' by the press landed the Segunda B side a Round of 16 tie against Racing Santander, which they lost 3-2. At the end of a season in which Real Madrid would score 102 league goals and finish second, AD Alcorcón won the Segunda B2, beating Ontinyent in a playoff which brought them to the second tier of Spanish football for the first time in their history.
