Alonso hits back at critics
Following his victory in the season opener in Bahrain Alonso was then involved in a first-corner collision with Michael Schumacher in the subsequent grand prix in Australia.
Rain during qualifying played havoc in Malaysia, with Alonso among a host of big names who started at the back of the grid after second guessing the weather and getting it wrong.
In China, the 28-year-old jumped the start and served a drive-through penalty before finally proving his worth again last Sunday in front of his home crowd in Spain by finishing second.
But on Saturday Alonso watched qualifying from the garage after putting his car in a barrier in final practice, with the damage meaning there was not enough time for his team to repair his car in time.
Alonso will now start from the pit lane, which means any chance of a points finish is virtually non-existent, and he is almost certain to relinquish second place in the Drivers' standings.
But as to his errors, Alonso snapped: "Do I think I've made too many mistakes this year?
"In Barcelona, where I was maybe under the most pressure, I did my best qualifying lap and had my best race.
"If, after 10 years in Formula One I still have to prove I do not feel pressure, then it's not worth talking about any more."
Alonso at least held his hands up to his Saturday shunt that saw him hit the barrier at Massenet heading into Casino Square which resulted in the loss of his right-front wheel.
But the resultant damage came as a major surprise.
"It was my mistake, but it was also very unlucky," he added.
"With an impact at 90 (kmh), you don't normally write off a chassis.
"Unfortunately the angle of impact with the barrier was such that the damage could not be repaired, and the rules don't let you use the spare chassis."
In starting from the pit lane, Alonso concedes he is now in "the worst possible place," but is refusing to give up hope.
He added: "We will do our best to bring home some points that can be useful for the classification." Planet F1
