Álvaro Arbeloa, that seems to live in an extraneous parallel world to the reality, ensured does some hours in an interview that the arrival of José Mourinho was very important for the Real Madrid, mainly because with the Portuguese technician the whites achieved "to break the hegemony of the FC Barcelona". The statistics of titles won by both teams during the period in that Mourinho trained to the Real Madrid, however say all the contrary regarding the supposed success of the technician luso.
In spite of being true that the numbers that had against the Barça were not of the all bad, neither were good. José Mourinho, like trainer of the Real Madrid, measured to the FC Barcelona in 17 Classical and only won 29,4% of them, five, four of these victories by the minimum.
The Portuguese, besides, has the honour to be the only trainer of the history of the Real Madrid that has been unable to win to the FC Barcelona in his first five clashes like venue in Santiago Bernabéu, suffering by the way atropellos like the 1-3 of the League 2011-12.
With Mourinho, besides, the Real Madrid obtained so only a League, a Glass of Rey and a Supercopa of Spain, whereas the FC Barcelona of Pep Guardiola conquered in the same period eight titles of importance: 2 Leagues (2011 and 2013), 1 Champions (2011), 1 Glass of Rey (2012), 2 Supercopas of Spain (2010 and 2011), 1 Supercopa of Europe (2011) and 1 World-wide of Clubs (2011).
This, without forgetting that the FC Barcelona deleted to the Real Madrid in some semifinals of UEFA Champions League, and that Leo Messi, Xavi Hernández and Andrés Iniesta coparon the nominations to the Balloon of Gold to the detriment of Cristiano Ronaldo while "Mou" exerted of technician merengue. "Mourinho was very important to break the hegemony of the Barça. No it has recognised him the sufficient. If it had not come, still we would have to Pep Guardiola in Barcelona winning titles", says Arbeloa. I suppose that everything is question of perspective.
