MOTORSPORT NEWS - Lewis Hamilton on Monday admitted to concerns about Mercedes' early-season form after seeing Ferrari’s Sebastian Vettel remain unbeaten in Sunday's Bahrain Grand Prix.
The 33-year-old defending four-time world champion said he had little idea how or why Ferrari had been able to out-perform his Mercedes team, Vettel claiming a tense win ahead of Valtteri Bottas.
It was the German’s second win in as many races this season and installed him as a clear favourite to beat Hamilton to become a five-time champion.
