Fernando Alonso won two Formula One World Championship titles during his 17 seasons on the circuit, but he is still unsure if he will make a return.
The Spaniard left F1 at the culmination of the 2018 season, and fans have been keen for the driver to make a comeback.
The 37-year-old has taken part in the FIA World Endurance Championship and the Indianapolis 500, but his exit from F1 is not due to a lack of confidence.
“As long as I have the power to do it, and I feel competitive,” Alonso said of his driving career.
“Maybe one day I jump in a Formula 1 car and there is one guy with the same car that is quicker than me.
“Or I jump in another car and one guy is quicker than me with the same car.
“As far as I know, it never happened so far. So I will still keep driving.”
Alonso is preparing to tackle the Indianapolis 500 for a second time next month, but spent some time this week testing McLaren’s 2019 F1 car.
When asked if he was looking to have fun whilst driving, he said: ”It’s something that probably has no precedent in the sport and I am looking for that, for challenges.
“It’s not to have fun. Sometimes I read that when I’m testing something that ‘we’re happy that you’re having fun but please come back to F1’.
“I’m not having fun.
“When I try one of those cars I have no idea. They need to tell me how they do it. Full throttle and brake at the same time, in rally style, and things you need to learn from zero.
“Definitely there is a lot of effort I put behind every challenge that I take, a lot of study behind it.”
James Allen, a former commentator for BBC and ITV, gave his take on Alonso’s possible return last month.
“If he had a car that he could compete with then I could see it,” Allen exclusively told Express Sport.
“He will still be able to compete, if you stuck him in a Mercedes or Ferrari now he could do well In the championship.”
