ABU DHABI (Reuters) - Lewis Hamilton could be only days away from his second Formula One world title but the Mercedes driver is wary of double trouble in Abu Dhabi on Sunday.

The Briton leads German teammate Nico Rosberg by 17 points going into Sunday's season-ending 'Duel in the Desert', which means he does not have to win the race to take the crown even with an unprecedented double points on offer.
