World No. 1 Novak Djokovic knows all too well the pitfalls that can come with getting on the wrong side of tennis officials, sympathising with Alexander Zverev following his expulsion from the Mexican Open.
Zverev travelled to Acapulco as the tournament's reigning singles champion, but his competition was cancelled early after he repeatedly clattered the umpire's chair with his racket following his doubles exit after a controversial line call on the penultimate point of the match.
The 24-year-old and partner Marcelo Melo lost on a champions tiebreak to Lloyd Glasspool and Harri Heliovaara, leading Zverev to react in a way that drew widespread criticism from fans and pundits alike.
