Jorge Lorenzo has shot down speculation in the Italian press that he and Marc Marquez had agreed a "pact" to stop Valentino Rossi from winning the MotoGP Championship.
Italian newspaper La Repubblica has claimed the two Spaniards held a secret meeting in Andorra at the end of September and planned to derail Rossi’s charge for a ninth MotoGP title.
During last weekend's Malaysian Grand Prix, Rossi appeared to stick out a leg that caught the defending world champions bike, causing Marquez to lose control of the bike and crash out of the race.
Rossi was handed three penalty points against his licence, meaning that he will start from the back of the grid at Valencia.
Prior to the Malaysian race at a press conference, Rossi accused Marquez of colluding with Lorenzo in the preceding race at Phillip Island to try and hamper him in his title bid.
Lorenzo's personal team have now issued a statement denying that there is any truth to the media reports that have been published over his alleged collusion with Marquez.
"We want to officially and categorically deny everything that has been published in the last hours about a possible meeting or pact between Jorge Lorenzo and Marc Marquez," the statement read.
"These reports published by La Repubblica, and which subsequently were copied by other Italian media, are ridiculous and unfounded.
"Without willing to contribute to this unpleasant situation for the rider, we just want to express our discomfort with this kind of rumours, which were not proven before being published.
"We reiterate once more that all this information is completely false."
The statement went on to add that after the race Lorenzo had never called for harsher penalties against his Yamaha teammate Rossi, which had been reported at the time.
"Likewise, we want to deny that Jorge Lorenzo was in the race director's office after the Malaysian Grand Prix like some have reported, and like Jorge himself explained during the press conference."
