Fernando Alonso, arguably the greatest natural talent to ever compete in motorsport, is returning to Formula 1 for the 2021 season. The Spaniard retired at the end of 2018, but will be joining Renault alongside Esteban Ocon next season. Alonso won the 2005 and 2006 world championships with the team, and also raced for them in 2008 and 2009.
