You don't spend 14 years on the ATP tour without hearing whispers of match-fixing.
Seasoned veteran Dudi Sela confirmed rumours of the plight which continues to plague tennis are not uncommon, but the Israeli has never been approached personally.
Sela, 31, spoke after winning the Canberra Challenger on Saturday, a tournament that featured Australian Brandon Walkin who was recently handed a six-month suspended ban for his involvement in a match-fixing scandal.
"I've never seen it but I've heard things. If it happens you must report it," Sela said.
The Israeli came from behind to defeat no.1 seed Jan-Lennard Struff 3-6, 6-4, 6-3 in front of a packed house at the Canberra Tennis Centre.
World no.87 Sela immediately broke Struff for a 2-0 lead, but the German rattled off six of the next seven games to clinch the opening set in 29 minutes.
The second set remained in the balance until Struff capitulated in the 10th game and gifted Sela both his service game and the set.
Struff looked cool, calm and collected all match until he spectacularly lost it during a third set meltdown that ultimately decided the contest.
After several dubious line calls the world no.64 reached his boiling point when he was broken in the second game of the deciding set and smashed his racket to earn a code violation.
Sela never relinquished his lead as the crowd favourite served out the match to secure his 21st Challenger title from 27 finals.
Israel's number one player was typically humble in victory and said it was only experience which earned him the $10,800 winner's cheque.
"It's always nice to win a tournament but I felt like he played much better than me today [Saturday], in the important points I was a bit lucky," Sela said.
"The experience of this stage, that I have been at so many times before, has taught me a lot, and also, to close out the match.
"He played very well but somehow every time it got to 30-30 I played a really good point, I'm happy I won but I think next time he will beat me."
Sela is one of the most popular players on tour and once again had strong support throughout his week in the capital.
"There were a few Israeli's here and it's nice to see the flag of your country all the way over here in Australia. It gives you something," he said.
"If they were not here I'm not sure I could have the motivation to come back and win like I did today."
Sela now heads for Melbourne where he will face world no.37 Marcel Granollers in the first round of the Australian Open.
"I've never played him before but it's a tough draw because he's been top 20 in the world and number one in doubles, he's a very good player," Sela.
"But I've never gone into the Australian Open having just won a tournament so this would have to be the most confident I've been going in."
Sela has advanced to third round in the past two Australian Opens and is gunning for a career-best fourth round berth at Melbourne Park this week.
