Barcelona - Real row escalates

For their part, UEFA announced disciplinary probes into the Mourinho sending-off and subsequent outburst at his post-match news conference.

Real midfielder Pepe and Barca reserve goalkeeper Jose Manuel Pinto will also face hearings after being shown red cards, while nine-times European champions Real will have to explain incidents of missile-throwing and a pitch invasion.

"We want to stand firm when the war of words passes certain limits and we believe Mr Mourinho crossed this line yesterday," Barca spokesman Toni Freixa told reporters after an extraordinary club board meeting.

"We are going to present a case to UEFA's Control and Disciplinary committee against Mr Mourinho for breaking UEFA's disciplinary code.

"It's unacceptable that anyone can question our titles or our link with UNICEF.

"It isn't our intention to fans the flames but to put them out, because we believe coaches should only talk about footballing matters and not things which could incite violence."

In a statement on their website (www.realmadrid.com) later on Thursday, Real said they had no choice but to respond with a representation of their own to UEFA and expressed their backing for Mourinho.

Barca had shown "non-sporting conduct" and their players had "persistently simulated aggression against them with the sole aim of provoking errors from the referee", the statement said, adding that Pepe's dismissal had been unfair.

The club said they were surprised disciplinary proceedings had been opened against Mourinho, who had only expressed his opposition to winning at all costs and his support for the principles of "loyalty, integrity and sporting spirit".

Barca's World Player of the Year Lionel Messi scored two superb goals after Pepe was sent off for a studs-up lunge at Barcelona's Daniel Alves in the 62nd minute. Mourinho was ordered from the bench for his protests over the incident.

After the match, Mourinho told reporters: "Josep Guardiola is a fantastic football coach, but he has won one Champions League which would embarrass me after the scandalous goings on at Stamford Bridge."

The Portugese was referring to the 2009 semi-final second leg in London when Barca snatched a 1-1 draw to qualify for the final. He said Chelsea should have had four penalties that were not given.

"This year if he wins it again it will be after the scandalous goings on at the Bernabeu," he added.

"I don't know if it's the UNICEF publicity or the friendship of Villar at UEFA, where he is vice-president, I don't know if it's because they are so nice, but they have got great power. The rest of us have no chance."
