Along with Sebastien Buemi, who moved to Red Bull’s reserve role, Spaniard Alguersuari was dumped by the energy drink company’s rookie team Toro Rosso.
A Barcelona native, the 21-year-old’s fans showed their support by displaying banners as the Circuit de Catalunya test began on Tuesday.
“I did nothing wrong, but I wasn’t killed either,” Alguersuari told the Italian magazine Autosprint. “I’m only 21 and I did my best with the equipment I had.”
One of the men who replaced Alguersuari, Daniel Ricciardo, backed Red Bull’s decision to make a clean-sweep of the Toro Rosso lineup for 2012.
“The only reason they kick you out is if you are not performing. And then you probably don’t deserve to be world champion,” the Australian is quoted by The Sun newspaper.
“That’s just the business we’re in.”
But Keke Rosberg, the 1982 world champion and Mercedes driver Nico’s father, criticised Red Bull for not giving Alguersuari a fair chance.
“They (Alguersuari and Buemi) had been there for three years and they (Red Bull) didn’t think they would go all the way to the top, so I understand if Red Bull wants to do something else.
“What I don’t understand is why the decision was made so late, when there was not anything else available for them.
“If someone says in June that they no longer need your services the following year, that’s fair. Then you have the time to find a new job.
“Buemi would probably have found something, if he’d have had more time,” added Rosberg.
