Barcelona lifted its fifth Champions League title a few weeks ago at the Olympiastadion in Berlin - a win that could, however, end up costing the club dearly.

The UEFA Disciplinary Committee has opened an investigation and is considering penalising the 'Blaugrana' club for the presence of 'Esteladas' (pro-independence flags) and the fans' chants calling for Catalan independence.

The Catalan club will present its arguments to the committee on 23rd July, the date on which a ruling on the case is expected. If a penalty is imposed, it could equate to a fine in the region of €60,000 and even include the partial closure of one of the Camp Nou stands.

UEFA wishes to make the clubs themselves accountable for crowd behaviour and everything that happens in the stadiums, wherever the games take place. This latest development has struck a blow at the heart of the club, currently undergoing elections, corresponding to an issue that needs to be resolved as quickly as possible.

This latest turn of events comes on the back of the controversy surrounding the booing of the Spanish national anthem during the Copa del Rey final against Athletic.
