The Ferrari president Luca di Montezemolo has launched a scathing attack on the recent Singapore Grand Prix saying the only thing the Marina Bay track is fit for is circus.
Renault's Fernando Alonso won the race Ferrari drivers Filipe Massa slipped from pole to 13th and Kimi Raikkonen crashed out.
F1's first night race drew rave reviews from spectators but drivers complained about how bumpy the track was, particularly off the racing line, which made overtaking difficult on a street circuit hemmed in by barriers.
There were two safety car interventions, the first of which turned the race upside down and contributed to Alonso's unexpected win for Renault.
Ferrari's failure to score any points in Singapore meant McLaren's Lewis Hamilton, who finished third behind Alonso, extended his championship lead over Massa to seven points with three races left.
