Hamilton, Rosberg return to scene of furious battle

Just days after their latest spat following Sunday's Chinese Grand Prix, Lewis Hamilton and Nico Rosberg return this weekend to the scene of one of their most dramatic on-track battles at the Bahrain GP.

World champion Hamilton emerged triumphant last year after a spectacular roller-coaster contest when he snatched victory ahead of his Mercedes teammate Rosberg.

German Rosberg, who has taken pole in Bahrain the past two years, knows he needs to complete a hat-trick of prime grid positions to give himself a chance of winning and reducing Hamilton's lead in the 2015 drivers' championship.
