Rubens Barrichello has this week continued his tirade against Ferrari and Michael Schumacher.

The veteran Brazilian, whose record-setting formula one career looks at an end, has followed through with his promise to one day reveal more about his six-year tenure with the famous Italian team.

On the Brazilian TV programme Fantastico, he claims he was threatened with the sack while he led the infamous 2002 Austrian grand prix.

While circulating in front of Schumacher, Barrichello said he was told over the radio: "Do you know that Michael is behind you? It's important for the championship."

He said his conversation with the pits lasted for eight laps, before an ultimatum was presented on the final tour.

"The intensity of the conversation increased with every lap. And then I was told to think about my contract," said Barrichello.

"For me it was clear -- take your foot off the gas or you will be going home."

Barrichello said he was appalled by the turn of events, and asked Schumacher afterwards if he had anything to do with the decision.

"He said he had nothing to do with it, but I have the documents at home to prove that he was aware of everything that took place," the 36-year-old insisted.
