Italian tennis player Yannik Sinner, a four-time Grand Slam tournament winner and world number one, will once again work with fitness coach Umberto Ferrara.
"Report" reports, citing "Ubitennis", that the Italian specialist and tennis player have worked together before.
The parties, who had been cooperating since 2022, parted ways last year after a doping scandal. It is reported that the decision to cooperate was made in preparation for upcoming tournaments, including Cincinnati and the US Open.
