Federer: "I understand people's frustration".

Although retired, Roger Federer never really left the world of tennis.

In New York this Tuesday, where he is expected to attend the quarter-final between Dimitrov and Tiafoe, the Swiss confided in our colleagues at "Today".

The man whose opinion is always eagerly awaited and respected spoke about the Jannik Sinner case.

As a reminder, the Transalpine had tested positive in March before finally being cleared after proving that the intoxication was involuntary.

While the case, and in particular the Italian's non-suspension during the investigation, continues to raise questions, the Maestro was kind enough to give his opinion: "We don't want to see this kind of news in our sport, whether he did something or not, or whether any player did something.

I understand that the situation is delicate.

I understand the frustration of people wondering if they've been treated the same as everyone else.

I think that's what it comes down to.

I think we're all convinced that Jannik didn't do anything, but the potential inconsistency comes from the fact that he wasn't put aside when they weren't 100% sure what was going on.

I think that's the question that needs answering.

The situation is what it is, and we have to trust the process as well as everyone involved in this case."
