Nick Kyrgios resumes online feud with Bernard Tomic, takes shot at compatriot's new training technique

Reigning Wimbledon finalist Nick Kyrgios recently rekindled his off-the-field rivalry with compatriot Bernard Tomic. Kyrgios once again indulged himself in a war of words with Tomic following the latter's "revolutionary" idea for tennis.

Renowned tennis journalist Ben Rothenberg recently shared a video on social media that shows Tomic riding a bicycle while playing tennis. In the video, he moves along the court on his bicycle, holding his racket as he returns his opponent's shot.

The Australian posted the video on his Instagram and sang the praises of his new-found "technique." He further added how he combined both of his "favorite training."

"Actually surprisingly good for coordination," Tomic wrote on Instagram. "Starting a new sport. My two favorite training combined."

Rothenberg reshared the video on Twitter and credited Tomic for the "revolutionary" idea.

"Leave it to the mind of Bernard Tomic to revolutionize tennis like this," he tweeted.

Kyrgios, however, took a different approach to Tomic's technique and resorted to social media to express himself.

"Moves better moving forward like this," Kyrgios wrote.

The online kerfuffle comes as a surprise to many as it comes just a few days after Tomic sent well-wishes to his countryman following his surgery. The former World No. 17 hoped for Kyrgios' speedy recovery.

"Despite our differences, we go way back. Wishing Nick Kyrgios a quick recovery, hope to see him back on the circuit soon," Bernard Tomic wrote on his Instagram story.
