"I do not currently see a reason," he added.
Sinner's lawyer said he thought the swift resolution of the case came down to taking an "unusual" legal approach."From day one [Jannik] didn't challenge the science, he didn't challenge the test, didn't challenge the rules," Singer told BBC Sport.
"He accepted, even though it's a trace - it's a billionth of a gram - he accepted that he was liable for what was in his body."And so we didn't waste time and money on all of those challenges, which traditionally defence attorneys would throw the kitchen sink at."We just focused on the evidence of what actually happened, and when we did that we managed to do that very quickly and demonstrate very plausibly what had happened."
Singer was also aware that the timing of the ban was as good as it could possibly be."We can't get away from the fact that you can't choose when these things happen," he said.
"So the fact that Wada approached us and in the next three months there are no Grand Slams, that seemed to me to make their offer more compelling."
Several players believe the timing was suspiciously convenient, with Britain's Liam Broady saying it had impacted Sinner's career as "little as possible".to be paid back over six years.
Part of this agreement was to help the airline keep providing islanders with "access to essential medical care".Mr Thompson said the government should be doing something to make sure people could rely on the service, and to make sure the money the health service spent on patient flights to Southampton was not wasted.
"It isn't acceptable," he said.He said: "It's not about me, it's about everybody who needs that treatment in Southampton, they deserve better than this... because in a lot of cases it can be the difference."
