In spite of that Viktor Kassai carried out a good arbitration during the majority of minutes in the Manchester City-Barça, can that he and his assistants failed when giving by valid the third goal of the group trained by Pep Guardiola to the FC Barcelona.

The Etihad Stadium was a clamour when seeing how the "citizens" sentenced the commitment in front of the culés, but the reality is that the "Kun" Agüero assisted with the arm to Ilkay Gündogan, in one of the passes backwards more curious of the last times in the Champions League.

The played, in cualuquier case, left a question in the air: it deserved the goal be cancelled? And it is that it is true that Agüero had the arm hit to the body in the action, but can that it threw to in front on purpose to send backwards the pass to the German midfield player.

The controversy is served, in any case, and sure that journalists and referees will have his own opinion in this regard. What is already definite is that, with this goal that went up to the marker, to the FC Barcelona already did him very slope up the rest of the meeting in front of the "citizens", a worthy rival that showed a distinct and more effective version that in the Camp Nou.

At the end, defeat of the FC Barcelona in the Etihad Stadium, that however does not do peligrar for the moment the classification of the Barça to the eighth of final of UEFA Champions League. With nine points, the blaugrana continue leading the table in the Group C.
