Fernando Alonso insists age will not be a factor when he makes his Formula One return in 2021.
The double world champion's comeback was confirmed on Wednesday by Renault. Alonso, who won back-to-back championships with the French team in 2005 and 2006, will celebrate his 39th birthday later this month.
He will also have spent two seasons out of the sport when he lines up for next year's opener and could be the oldest driver on the grid if 40-year-old Kimi Raikkonen calls time on his career.
He returned to the French manufacturer before a four-year period at Ferrari where he came close to winning the title on two occasions.
After falling out with the Italian team, he went back to McLaren, but the switch proved desperately unsuccessful.
Alonso quit the sport after four seasons with McLaren, setting his sights on becoming only the second driver since Britain's Graham Hill to complete the so-called Triple Crown – winning the Monaco Grand Prix, Le Mans 24 Hours and Indy 500.
Although he won the famous sports car endurance race in 2018 and 2019 he has not been able to crack the Indy 500, despite a remarkable effort on his first appearance back in 2017.
