May 14 (GMM) Michael Schumacher will start next Sunday's Monaco Grand Prix five places lower than he qualifies.
Despite the furious seven time world champion moaning "idiot" on the radio after the incident, stewards found him guilty of causing the rear-end crash with Williams' Bruno Senna.
"It was clearly Michael's fault," triple world champion Niki Lauda told Bild newspaper, whose headline slammed 'Rambo Schumi'.
Brazilian Senna, whose famous uncle Ayrton raced against Schumacher until his death in the mid 90s, replied: "Michael shouldn't call me the idiot.
"I didn't crash into him. Yes, I braked earlier with my old tyres, but Michael should have enough experience to anticipate that."
The FIA stewards agreed, ruling that 43-year-old Schumacher must drop five places on the grid in Monaco.
"That was completely Michael's fault," former Toro Rosso driver Jaime Alguersuari said on British radio BBC 5 Live.
"He ran into the back of Senna's car without an intention of overtaking."
