Novak Djokovic leaves a heartfelt message for Juan Martin del Potro

Novak Djokovic admitted that he was saddened by Juan Martin del Potro's retirement. The Argentine star retired in 2022 but will compete in a farewell match against Djokovic in Buenos Aires.

Speaking ahead of the match, Djokovic sympathized with Del Potro and his injury record. The Serbian star said that del Potro would have had a legendary career if not for all his injury concerns.

"His career is legendary as it has been, but I believe that, as all of us here would agree, he has had bad luck with injuries. Surely his career could have been greater if he had not had knee injuries. I have had some serious injuries, but not with such bad luck as him," Djokovic said.

WADA director makes major claim after Iga Swiatek and Jannik Sinner doping tests

Niggli claimed that tennis players could be easily contaminated by doing harmless things. He further added players have to be a bit more careful to avoid such issues.

"Today there is a contamination problem. This does not mean that there are more cases of this kind than in the past, the fact is that laboratories are more efficient in detecting even infinitesimal quantities of substances. The quantities are so small that you can get contaminated by doing harmless things," Niggli told L'Equipe.
