Novak Djokovic said he is "heartbroken" after his former coach Boris Becker was handed a two-and-a-half year prison sentence.
Becker was found guilty of four charges under the Insolvency Act last month, and will serve at least half of his sentence behind bars.
The German was convicted of hiding a number of assets, including nearly £700,000, 75,000 shares in a tech firm and some of his most prized tennis titles - including two Wimbledon trophies. Becker was legally obliged to declare all of his assets after being declared bankrupt five years ago
