MADRID - Spanish footballing giants Barcelona and Valencia on Monday rejected allegations by a Spanish radio station that they may be involved in doping.

Barcelona "wishes to publicly express its total indignation at these unfounded references which link the club to doping practices" while Valencia described the allegations on the Catholic radio station Cadena Cope as "false".

Cadena Cope on Sunday quoted a "representative" of Real Madrid, who was not identified, as saying the club planned to "ask the Spanish football federation for serious anti-doping controls".
