Former Barcelona president Joan Laporta says Real Madrid are behind the recent doping allegations made against the Spanish Liga leaders.

Cope cited an unnamed Real representative as the source, but Real president Florentino Perez phoned his Barcelona counterpart, Sandro Rosell, to assure him that Real had nothing to do with the allegations.

However, Laporta has told Catalunya Radio: "It is clear that Real Madrid are behind the doping accusations against Barcelona.

"I don't think it was enough that he (Rosell) excused the president of Real Madrid (Perez) because he had a telephone conversation with him."
