A Berlin court has begun hearing an appeal by the German tennis player Alexander Zverev against a fine imposed on him for allegedly assaulting his girlfriend, an accusation which he denies.
As the world No 4 competes at the French Open in Paris, his lawyers are fighting his case in court, after he was fined €450,000 (£384,000, $489,000) in October for allegedly trying to strangle Brenda Patea, his then partner and the mother of his three-year-old daughter, Mayla.
