LewisHamiltonfears he will be the underdog in the remaining six races of the Formula One season. Hamiltonheads into this weekend's Russian Grand Prix with just two victories from his last seven appearances - and a disappointing fourth in Singapore last weekend - while a resurgent Ferrari bid for their fourth win in succession.

Mercedes are unbeaten at the Sochi Autodrome, winning all of the five races staged here.

ButHamiltonbelieves Ferrari drivers Sebastian Vettel, who ended his 13-month losing streak in Singapore, and Charles Leclerc hold the aces - not just ahead of Sunday's race, but for the remainder of the campaign.

"We will not be favourites at any of the next six races," saidHamilton. "It is not my job to worry, but we are conscious of the position we are in.

"We know how fast Ferrari have been on the straights, so for us there isn't a short-term fix, but there are other areas we can do better in.

"At the last three races, we haven't extracted 100 per cent from the weekend and that is what we need to get back to. I can squeeze more out of the car, more out of myself. I haven't done a perfect lap yet this season."
