Novak Djokovic, assured of ending the year as number one and winner at the Barclays ATP World Tour Finals, let off some steam in a weekend exhibition match as he impersonated three-time French Open champion Gustavo Kuerten.

The Djoker faced the Brazilian in an exhibition match in Rio de Janeiro for the inauguration of a public court in the Rocinha shantytown on Friday.

More than 10,000 people packed Maracanazinho Arena for the indoor match on clay to see the Serb do his best 'Guga' effort.

Djokovic then joined Kuerten for a game of football before a Brazilian league match on Sunday.
