On 3 March 2011, Real Madrid welcomed their former manager back to the Bernabeu by crushing his new team 7-0.
The manager in question was Manuel Pellegrini, who had taken charge of Real Madrid in June 2009 for their second Galacticos period that saw them acquire Kaka, Cristiano Ronaldo, Xabi Alonso, and Karim Benzema for an approximate total of £200M in transfer fees. But after only one season--in which they finished as league runners-up to Barcelona--the club sacked Pellegrini in order to hire José Mourinho.
In November 2010, Pellegrini signed a three-year deal to manage Málaga. They had already lost to Real Madrid in the league the previous month, so the game in March was his first time facing his former employers.
It was a rout. Two of Pellegrini's signings scored a total of five goals (three from Ronaldo and two from Benzema), while Ángel di María and and Marcelo added goals of their own to stretch the margin to 7-0. When the final whistle blew, Málaga were down to nine men, with one ejected and one injured after Pellegrini had made all three substitutions.
Although the loss sent them down to 19th place, things did get better for the club. They finished the season in eleventh, and are currently sitting in sixth this season.
