Mercedes's Toto Wolff: 'Lewis Hamilton breaking down would be a nightmare'

Mercedes boss Toto Wolff is desperate for drivers Lewis Hamilton and Nico Rosberg to avoid any mechanical difficulties in the final race of the Formula 1 season in Abu Dhabi.

Hamilton currently has a 17-point lead over his teammate in the driver rankings, but the season-ending showpiece offers double points.

"Clearly Lewis breaking down would be a nightmare," BBC Sport quotes Wolff as saying. "We want the championship to end in a straight and fair battle and not by one of them breaking down."

Hamilton will clinch the title if he finishes first or second in Sunday's race.
