Mercedes driver Valtteri Bottas has admitted that his 2018 Formula One season was the most disappointing of his career.
Bottas failed to score a victory all season while teammate Lewis Hamilton won the title with 11 wins from 21 races. Bottas came close to victories this year -- not least in Russia when Mercedes ordered him to hand the lead of the race to Hamilton -- but said not having a victory in such a competitive car meant 2018 ranked as a low point in his career.
"Yes, I think it is," he said when asked if 2018 was his most disappointing season.
