The entire Ferrari team has sent a message of encouragement to Formula One driver Jules Bianchi, who is fighting for his life following an accident at the Japanese Grand Prix one week ago.

The two drivers, Fernando Alonso and Kimi Raikkonen, flanked team chief Alberto Mattiacci, behind a sign reading "Forza Jules" (Go Jules).

The gesture came on Sunday, shortly before the inaugural Russian Grand Prix.

Bianchi suffered a severe head injury when his Marussia car skidded off the wet course at Suzuka and ploughed into a tractor recovering another car that crashed out at the same spot one lap earlier. His condition is critical.

Bianchi, a Frenchman, drives for Marussia but is a member of Ferrari's young drivers academy.
