Frosty reunion likely for Ferrari foes

(GMM) Michael Schumacher and Rubens Barrichello are this weekend likely to endure a frosty reunion in Brazil.

The pair, formerly teammates at Ferrari, are among those confirmed to compete in the charity 'International Challenge of Go-Kart Champs' race, organized by Felipe Massa in the southern city of Florianopolis.

Barrichello, whose long formula one career appears over, has been vocally critical of Schumacher recently, including this week's provocative claim that he has "documents to prove" that the seven time world champion was directly involved in the team orders saga of Austria 2002.

Schumacher, 39, reacted to Barrichello's musings about his status at Ferrari by insisting the Brazilian had not been fast enough.

"Nobody can make you slower because of a contract," he said recently. "If you are fast, you are fast, and then you are the number one."
