Lewis Hamilton: Singapore Grand Prix will be a big challenge for Mercedes

Lewis Hamilton’s Mercedes team have admitted they are not the favourites to win Sunday’s Singapore Grand Prix after being off the pace at the street circuit last year.

Hamilton and team-mate Nico Rosberg were inferior to both the Red Bulls and Ferraris at the Marina Bay track in 2015.

Hamilton failed to finish after suffering mechanical gremlins, while Rosberg could cross the line only in fourth, 25 seconds behind race winner Sebastian Vettel.
