Felix Sturm suggests Sam Soliman is lying over his denial that he took drugs Felix Sturm (left) has questioned Sam Soliman's (right) honesty after Soliman insisted he had not taken drugs despite returning a positive sample to oxilofrine. SAM Soliman's management will demand the B sample of his positive drug test be opened in Australia, while opponent Felix Sturm has questioned his honesty. A test taken prior to Soliman's IBF middleweight boxing title eliminator win over Germany's Felix Sturm in Dusseldorf last month revealed the prohibited substance oxilofrine. After the test result was revealed last Sunday, Soliman tweeted drug allegations against him were complete nonsense and an insult and the matter was in his lawyer's hands. Sturm turned to Twitter himself to demand the IBF alter the fight result to a no contest and also questioned Soliman's honesty. "In my opinion Soliman should do himself a favour, stop lying and confess his wrongdoing," Sturm tweeted. His A-sample was positive and that was confirmed by both the NADA (German national drug testing agency) and WADA (World Anti Doping Agency). Come on, Sam, stop lying. Or are you trying to tell me that someone slipped you a drug? One that's difficult to find? That makes no sense to me. No sense at all. Sturm said Soliman had taken a substance that was hard to trace and invited the Australian to return to Germany for the opening of his B sample. Soliman's manager David Stanley said his legal team were working towards getting the B sample being opened in an independent Australian laboratory. "We won't be travelling to Germany, we require the B sample to be sent to Australia to a WADA approved organisation," Stanley told AAP. We just think it's absolutely appropriate and Sam Soliman's right that the sample come into a WADA-approved laboratory in Sydney. Sam Soliman is not a drug cheat, we here in Australia know his values in that regard. I've got no issue with Sturm coming to Australia or sending a representative to go through the B sample. Stanley reiterated complaints about what he perceived as the Sturm camp's failure to comply with all the drug testing requirements in the fight contract. He said while the situation had become very messy, he had no regrets about insisting on pre-fight drug testing. "We do not resile, WADA testing should be universal right through boxing," Stanley said. The negotiating period for Soliman's mandatory challenge to IBF champion and compatriot Daniel Geale has ended, with the IBF asking for more time to consider the position before heading to purse bids for the fight.
