Both Barcelona and Real Madrid will face disciplinary proceedings from UEFA after their tempestuous Champions League semi-final first-leg tie at the Bernabeu - while Barca will make their own complaint about the behaviour of Jose Mourinho.
Barcelona won the game 2-0 thanks to two goals from Lionel Messi, but the clash was littered with unsportsmanlike behaviour, diving and fights. After the match, Real boss Jose Mourinho (who had been sent to the stands during the game for comments made to the fourth official) then launched into a tirade about the influence that the Catalan side have over European football.
A statement on the UEFA website read: ''Following last night's UEFA Champions League semi-final first leg between Real Madrid CF and FC Barcelona, UEFA has opened the following disciplinary cases against the clubs.
''The case against Real Madrid is in relation to the throwing of missiles, a pitch invasion, the red card shown to Pepe, the dismissal of coach José Mourinho, as well as the inappropriate statement given by Mr Mourinho to the media after the match (UEFA Disciplinary Regulations, Article 5 - Principles of conduct).
''The case against Barcelona regards the red card administered to José Pinto. Both cases will be heard by the UEFA Control and Disciplinary Body on Friday, May 6.''
Barcelona had already claimed that they would be looking to take Mourinho to UEFA after he made the claim that the club's sponsorship deal with charity UNICEF meant they were treated favourably by officials. The club have Barcelona confirmed they will report the coach to European football's governing body.
"Jose Mourinho severely criticised the referee Herr Stark and insinuated that UEFA treated Barca favourably. The club's legal department are now studying whether to take his remarks to the UEFA disciplinary commission," Barca said in a statement on Thursday morning.
Barca club secretary Antoni Freixa Martin added on Thursday evening following an emergency board meeting: "Yesterday Mr Mourinho went over all the limits. We trust in UEFA measures. The president decided to convene a special meeting and we will report the coach of Real Madrid to the Control and Disciplinary Committee of UEFA for his statements. They constitute a fraction of Article 5. Barcelona feels hurt.
"We cling to point B and D of the article because we feel the club's reputation has been damaged. We have reacted because there has been an offence against the club, players, staff and fans."
Just hours after Barcelona confirmed they would be reporting Mourinho, Real Madrid announced they are going to report Barcelona to UEFA for alleged "unsportsmanlike behaviour" during Wednesday night's clash.
A statement on the Madrid website read: "Upon learning of the unprecedented decision made by Barcelona to lodge a formal complaint against Real Madrid coach Jose Mourinho with the UEFA Control and Disciplinary Body, Real Madrid announces that it is obligated to do the same concerning the repeated unsportsmanlike behaviour of Barcelona, whose players consistently feigned aggressions with the sole purpose of misleading the referee of the match, which clearly led to the unfair decision to dismiss our player Pepe.
"It is surprising that this chain of unsportsmanlike conduct and unfortunate decisions finally culminates in the filing of a complaint against our head coach Jose Mourinho who, beyond opinions based on his right to freedom of speech, expressed his objection to victory at any price and the violation of the principles of loyalty, integrity and sportsmanship established in Article 7 of the Preamble of the UEFA Statutes and Article 5 of its disciplinary regulations, by which Real Madrid expresses its full support of its coach."
