It is used to to be a tonic dominant in the last times that when there is a party of Champions League in the Camp Nou, touch pitada monumental to the hymn before the crash. What really has surprised in this occasion was that the general boo produced in the Etihad Stadium, before the victory of the Manchester City on the FC Barcelona (3-1).

The bloated of the English team and the one of the Catalan group jointed in his criticisms to the estamentos of the maximum organism to European level of the football. Although the Barcelona struggle by his right to lucir the flags independentistas in the parties, the protest of the "citizens" is something distinct.

In fact it has two causes in his origin. One of them does to trace back to the year 2014. It was then when the UEFA penalised to the Manchester City with a sanction in terms of Fair playfinancial . This yes, the English did not finish to suffer it of the all since it raised him in 2015. 

The another origin of the pitada by part of the venues also is due to this same years. It was by the party that the Manchester contested in front of the CSKA of Moscow and that owed to play to enclosed door. However, some fans achieved to go in unlike the English. This is something that inflate them never will forgive, as they took it like a lack of respect of which the UEFA never excused.
