The world tennis number one Novak Djokovic is fuming about the court that will be used for Serbia's Davis Cup first-round tie this weekend in Belgium.
Djokovic says the clay surface which has been laid on top of a parquet floor is the
worst court they've ever played on, and he's concerned for their well-being.
The world number one, playing for his country for the first time since September 2011, also said he was still jetlagged after beating Britain's Andy Murray at the Australian Open final last Sunday.
