Barcelona have confirmed a board meeting will be held later today as the club consider action against Real Madrid coach Jose Mourinho.
Mourinho implied the Catalan giants receive favourable treatment from referees and claimed the club had yet to win a 'clean' Champions League title under Pep Guardiola.
The outburst came shortly after Guardiola's side won 2-0 at the Bernabeu in the first leg of their Champions League semi-final with the Portuguese particularly angry at the dismissal of makeshift midfielder Pepe for a challenge on Dani Alves.
Barcelona's directors are due to convene at 5pm to discuss how best to move forward.
Sent to the stands: Mourinho was dismissed from the touchline during the ill-tempered semi-final clash
A statement on the club's website this morning read: 'There will be an 'extraordinary' meeting of the board to discuss the action to be taken after the events of the Bernabeu.
'Later there will be a press conference (6pm BST).
'At the press conference after the game, Real Madrid coach Jose Mourinho harshly criticised referee Wolfgang Stark and suggested Barcelona receive favourable treatment.
'The Legal Services of FC Barcelona are considering reporting the Real Madrid coach to the Disciplinary Commission of UEFA.'
Mourinho's anger stemmed from the decision of German referee Wolfgang Stark to send off Pepe for a foul on Dani Alves on the hour mark, with the former Chelsea boss being sent to the stands too for his protests.
Mourinho said: 'Guardiola is a fantastic coach, but he has won one Champions League which I would be ashamed to win after the scandal at Stamford Bridge and this year, if he wins it again, it will be after the scandal at the Bernabeu.
'I hope that one day he will win a clean Champions League, with no incidents behind it.'

The first 'scandal' Mourinho was referring to was the Champions League semi-final between Barca and Chelsea in 2009, when the Catalan club progressed through to the final following a controversial second leg in London.
Andres Iniesta's injury-time strike earned Barca an away-goals win, but at the final whistle Chelsea's players confronted referee Tom Ovrebo, who had waved away at least four penalty appeals during the game. Barca would go on to beat Manchester United in the final.
Mourinho, who last season saw his Inter Milan side reduced to 10 men in the second leg of their Champions League semi-final at Barca but still progressed through to the final, did not stop there either in his post-match rant last night.

He added: 'Today it's clear that against Barcelona you have no chance. 'I don't understand why. I don't know if it's the publicity of UNICEF (the club's shirt sponsor), I don't know if it's the friendship of (Spanish football federation president Angel Maria) Villar at UEFA, where he is vice-president, I don't know if it's because they are very nice, but they have got this power. The rest of us have no chance.
'Why couldn't Chelsea reach the final two years ago? It was a miracle that Inter reached the final last year.
'I am here just to ask this question and I hope to get the answer one day.'

Regarding the match itself, which saw Lionel Messi score two late goals to earn Barca the victory, Mourinho believes it is now 'mission impossible' for his side to progress through to the final.
However, Barca boss Guardiola is not assuming the tie is already over heading into next week's second leg at the Nou Camp.
'We are a step away from the final, but we will carry on respecting Madrid, very, very much,' said Guardiola, who refused to respond to questions about Mourinho's comments.
'If we start to believe we are already through, Madrid can punish us. We don't believe we are already there (Wembley).'
