Formula One champion Lewis Hamilton says he has unfinished business to take care of in this weekend's Belgian Grand Prix.
The McLaren driver took a thrilling victory at the Spa circuit last year on his way to the title but was then demoted to third place after a chicane-cutting controversy.
Hamilton started the season with a car so uncompetitive that McLaren immediately ruled out being able to challenge for victories.
The champion has long given up on any hope of defending his crown.
However the Mercedes-powered team have made huge strides over the months since the season-opening in March, allowing Hamilton to hope for another strong performance at one of Formula One's great tracks.
