Andre Villas-Boas, former manager of English Premier League football teams Chelsea and Tottenham, will compete in the 2018 Dakar Rally.
The Portuguese, aged 40, will compete behind the wheel of a Toyota Hilux in the car category, with former motorcycle class frontrunner Ruben Faria joining him as co-driver.
Villas-Boas said he considered contesting the race on a bike before heeding advice to enter the car category instead.
"I spoke with my friend Alex Doringer, the manager of the KTM team, who told me that I would still need a full year's preparation to get there [on a bike] and that it was better to consider doing it with a car," Villas-Boas said.
"So I got in touch with Team Overdrive [Toyota] and here I am!"
As a manager, Villas-Boas won the UEFA Europa League with Porto in 2011, joining Chelsea at the conclusion of that season.
He departed the English team without overseeing a full campaign, and later joined another London-based outfit in Tottenham, where he stayed for a year and a half.
More recently, Villas-Boas managed Russia's Zenit St Petersburg and China's Shanghai SIPG.
His Dakar 2018 co-driver Faria has been a regular competitor in the event with KTM over the past decade, finishing runner-up to team-mate Cyril Despres in 2013.
He retired from full-time bike competition last year.
"When Andre called me to propose that I join him, I had to think about it... for at least five seconds," Faria said.
"It is a great challenge and I think that we can put in a good Dakar, which means making it to the bivouac every night and not to arrive too late!"
The 2018 Dakar Rally - the 40th edition of the event - will take place between January 6-20, spanning Peru, Bolivia and Argentina.
