After overcoming 20-times Grand Slam winner Federer in the semi-finals in London on Saturday, the 21-year-old Zverev beat world number one Djokovic 6-4 6-3 the next day to claim the biggest crown of his career so far.
Becker, a six-time Grand Slam winner, said Zverev had the potential to be the new superstar of world tennis and backed his compatriot to deliver on his promise under coach Ivan Lendl.
