Alexander Zverev has sparked rumors of hiring Toni Nadal, Rafael Nadal's uncle, as his coach for the Australian Open.
Previously, Daniil Medvedev trained with Toni Nadal for ten days in July before the North American hard-court swing.
Zverev is seeking a coach to boost his confidence after a poor performance on the ATP Tour, particularly during the Asian swing.
No official statement has been made by Zverev regarding the hiring of Toni Nadal.
