Djokovic relishing new Davis Cup format
Tennis star Novak Djokovic backed the new Davis Cup format on the eve of Serbia's opening match against Japan.
World number 2-ranked Djokovic leads out a powerful Serbia team which will be wary of taking Japan lightly after top nations Croatia and Italy both suffered shock Day 1 losses to an understrength Russia and Canada, respectively.
The 32 year-old had been under an injury cloud in the lead-up to the revamped finals, in Madrid, having injured his elbow in the ATP Finals loss to Rodger Federer.
Having come through a practice session unscathed, the Serbian great confirmed his place in his nation's line-up to contest the finals.
Djokovic is joined by Dusan Lajovic, Filip Krajinovic, Viktor Troicki and Jamko Tipsarevic.
