Webber has long clashed with Marko, who told Red Bull’s own magazine earlier this month that the Australian was unable to find the consistency needed to handle the pressure of F1.
However, Webber responded: “Look, everyone at this level has their own agendas and it’s been evident for a long time now that I’ve never been a part of Marko’s.”
Webber has played second fiddle at Red Bull for the past three seasons, with team-mate Sebastian Vettel winning the F1 title on three successive occasions.
The Australian, who is now 37, is only on a one-year deal with Red Bull this season and after undergoing surgery recently to remove a titanium rod from his leg, after a 2008 cycling incident, he said he was feeling fit and healthy.
“The surgery went very smoothly and my recovery was exceptional,” he said.
“I had a few weeks off from my normal training schedule but I was able to ease myself back into it by the first week of January and now I’m back into it properly.
“I didn’t really know what to expect from having it removed, apart from my own peace of mind, but I’m very happy that some of the niggles and pain I’ve sometimes experienced with my training over the past three years already seem to be a thing of the past.”
