Lewis Hamilton believes Mercedes teammate Valtteri Bottas will be a genuine threat in the title race this year.
Bottas took the first win of his Formula One career at the Russian Grand Prix two weeks ago and drew within 10 points of Hamilton in the drivers' standings, who in turn is 13 points shy of championship leader Sebastian Vettel. Just two weeks earlier, Bottas had been asked to move aside for Hamilton at the Bahrain Grand Prix but Hamilton has no doubt his teammate can mount a title challenge this season.
"Of course he's a credible competitor [for the title], he was when he joined," Hamilton said.
