Last month, Becker, 54, was handed a two-and-a-half year prison sentence after failing to declare £2.5 million worth of assets to avoid paying debts.
The German, who won Wimbledon three times, was Djokovic’s coach between 2013 and 2016, with the pair enjoying a fruitful spell together.
Speaking this week, Djokovic revealed he is still finding it hard to deal with Becker’s downfall.
He said: ‘It breaks my heart to see what happened. We had a great relationship throughout my career. I talked to his son Noa, asked if there is anything I can do. It’s just sad, I hope that he stays healthy and strong.’
Djokovic is currently playing at the French Open, where three straight-set wins have left the 35-year-old in good shape heading into the business end of the tournament.
The Serbian is aiming for a third title at Roland Garros and 21st grand-slam triumph overall.
His arch-rival Rafael Nadal, who he is on course to face in the quarter-finals, nudged ahead in the race to finish with the most grand-slams after winning his 21st at the Australian Open in January.
Despite the likes of 19-year-old Spaniard Carlos Alcaraz being tipped for success this week, Djokovic believes experience will be key in the French capital.
He next faces Diego Schwartzman in the fourth-round on Sunday on Court Suzanne Lenglen.
Djokovic added: ‘But, you know, Grand Slam is different, playing best of five. So, of course, the experience that Rafa and I have and guys like (Stefanos) Tsitsipas and (Sasha) Zverev that have been already there for a few years, could help.’
