Barcelona is ranked as the best football team currently because of their style of football and the achievements over the years.
The questions being asked by their opponents, neutral fans and other clubs (behind closed doors not to risk punishment by the governing body) in the football world are; if they are already that strong, always dominating possession, why do officials' decisions or indecisions seem to tilt the balance in their favour particularly when they are struggling? Are the officials influenced to bin impartiality? Is UEFA, for the sake of marketing the sport as a beautiful game and rejection of defensive teams, behind it? Is it a Conspiracy or just a Coincidence?
