May 16 (GMM) Jaime Alguersuari has told Spanish publications he is "absolute certain" he will be on the 2013 grid.
"This is the best year of my life," he told Mundo Deportivo, referring to 2012, the year after his young F1 career stalled when he was dropped by backer Red Bull.
"I'm only 22," said Spaniard Alguersuari, who is now Pirelli's main test driver and a co-commentator for British radio. "I'm in the prime of my life.
"It is increasingly clear that what happened with Toro Rosso was not a sporting decision. It was an internal decision and I don't want to go deeper."
He sounded confident about the future.
"It is 100 per cent that I will return in 2013. After being with Pirelli I will have very important knowledge. I knew that this transitionary step was necessary and I'm very happy," said Alguersuari.
"If I had gone (to be test driver) with a team, with all due respect, I'd have no options now.
"I am developing a product (Pirelli) that nobody understands but that is vital for Formula One -- to know the tyres and to understand them. I'm in the right place," he is quoted by La Vanguardia newspaper.
"I chose to be with Pirelli because I knew it would be the most important (element) in Formula One.
"I know where I am and I know where I'll be next year," he insisted.
