Wimbledon 2013: Frederik Nielsen claims he has been a target for match fixing I would never do it, but I understand it could sound like a good idea to take 30,000 to lose Challenger match - though I don't know whether that is a realistic amount - where if you win you only get €1,000. These players have families to feed. He said he had been approached on other occasions, without a firm offer being made. People are sneaky by asking questions very indirectly, so it can't come back and get them. I think it sucks because it goes against the values that I stand for. Nielsen added there had seen several matches where he wondered if the result had been influenced by one of the players being paid to lose. But it is a difficult problem to tackle. What do you do it? How do you find out?" he said. Tennis is very easy to influence because it is only one player. It is a problem that can grow bigger and bigger, and we have seen a lot of players convicted of it. The interview came after a busy few months for the International Tennis Federation, which is charged with stamping out corruption in the sport. In June, Dutch player Yannick Ebbinghaus was fined $10,000 and barred from competing for six months after it emerged he betted on tennis matches, which is banned under Federation rules. A week previously the Russian Sergei Krotiouk had been given a lifetime ban from the sport for match-fixing, the third man in two years to be so. He was also fined $60,000.
