F1: 5 of the most controversial moments of Alonso's career

#4 Blocking Massa during qualifying - 2006 Italian Grand Prix

Fernando Alonso was penalised for blocking Massa during the 2006 Italian Grand Prix qualifying session

Along with the 2006 Hungarian Grand Prix, Fernando Alonso was also involved in another controversy during the Italian Grand Prix.

The Spaniard was penalised by the stewards for blocking Ferrari's Felipe Massa during the qualifying session at Monza. This demoted the then champion from fifth place to the tenth place on the grid.

Fernando Alonso was clearly upset with the decision as the Spaniard felt that the stewards were unjust to his cause, and uttered the infamous words 'I no longer consider F1 a sport.'

However, all that didn't matter as Alonso suffered an engine failure during the race, which only added to his woes in what was already a frustrating weekend for the Spanish driver.
