Fernando Alonso says his Formula One future will depend on the direction the sport takes over the coming years and whether it can put the focus back on drivers.
Alonso won two drivers' championships in 2005 and 2006, but a series of poor career decisions and missed opportunities have seen him finish runner-up three times since then without securing another title.
Since the introduction of F1's turbo hybrid engines in 2014, Alonso has not won a race or finished higher than sixth in the championship, and he last fought for a title in 2012 -- when he missed out by three points while driving for Ferrari.
