Jannik Sinner has made the tough decision to part ways with two members of his coaching team after recently returning from a three-month doping ban.

The Italian world No.1 is confirmed as the Wimbledon top-seed for the first time as he seeks to better his quarter-final result 12 months ago.

However, he must do so without fitness trainer Marco Panichi and physiotherapist Ulises Badio, with Sinner opting for change.

Sinner, 23, twice tested positive for an anabolic steroid during Indian Wells in March last year, but was allowed to continue to play on until February when the ruling was made.

Just days after the doping case was announced to the public, the three-time Grand Slam winner separated from fitness coach Giacomo Naldi and physio Umberto Ferrara, with the latter blamed for negligence.

Panichi and Baldo were hired in September to join the coaching setup with Simone Vagnozzi and Australian Darren Cahill.

"He's fine, we arrived in London a couple of days ago, we are training, and the first sensations are good," Vagnozzi told Ubitennis ahead of Wimbledon. "Jannik is training hard, we hope to put in the right 'fuel' to get to the first-round."

Sinner seeks to bounce back following a heartbreaking defeat to Carlos Alcaraz at the Roland-Garros final, where he squandered three consecutive championship points.

He commences his Wimbledon campaign against compatriot Luca Nardi.
