Madrid - Barcelona have denounced allegations in a Spanish radio station report "which link the club to doping practices."
Cadena COPE claims Barcelona rivals Real Madrid have asked the Spanish football federation to take drug testing "more seriously" as they don't understand how "doctors with questionable reputations" can be associated with the Catalan club. COPE did not name which doctors Madrid were referring to.
Barcelona said in a statement they are "demanding immediate rectification" as they study legal action to "to defend the club's honour, alongside that of their coaching staff, players and medical staff."
Valencia also threatened COPE with legal action after they claimed Operation Puerto doctor Eufemiano Fuentes worked with the club.
