Barca, Real may abandon domestic league - Valdano
Barca crushed Villarreal, who are competing in this season's Champions League, 5-0 at the Nou Camp on Monday, while Real demolished Real Zaragoza 6-0 away the previous day.
The results prompted the president of Villarreal to accuse Barca and Real of killing Spanish soccer, while the Sevilla president said La Liga was "a load of rubbish".
The dominance of Barca and Real derives in part from their control of revenue from television rights, which gives them a far bigger share of the pot than rivals in other major European leagues.
Spain has yet to adopt the system of collective bargaining and income sharing used in other competitions like the English Premier League.
Javier Faus, a vice president of Barca, told Reuters in February the club would like to see an expanded Champions League and floated the idea of reducing the number of clubs in top domestic divisions to free up time for more continental matches.
However, he said it was unlikely Barca or Real would ever quit domestic competition entirely.
"We are going through a period of transition, it depends what happens in Spain and other leagues," Valdano told Cadena Ser, which has hired him as a commentator.
"The problem is that the Premier League works, Germany works. There is a lot of passion for football. I don't see them being very enthusiastic about leaving their national leagues."
