Penrith Panthers director Greg Alexander launches attack at Todd Greenberg PENRITH director and rugby league great Greg Alexander has launched a stinging attack on under-siege Todd Greenberg, claiming the new NRL head of football has "pulled the wool over everyone's eyes." Alexander also claimed Greenberg's position was now "untenable." "He has hidden a potential timebomb from his employers," Alexander told Sports Today. Greenberg and the Bulldogs are under heavy scrutiny for their handling of the ugly Ben Barba affair. In February this year, Greenberg held a press conference where he claimed Barba was being stood down from rugby league due to alcohol and gambling reasons. He was to enter rehabilitation. Greenberg has also denied rumours Barba had allegedly assaulted his partner Ainslie Currie. NRL head of football Todd Greenberg. Alexander went on the attack Tuesday night, saying: "I don't know how Todd Greenberg thought he could keep this a secret. It is impossible to keep a secret these days. When he left club land for the NRL, he had to tell his bosses, who had just employed him to a position of power, that we could have a problem. He has taken his position of trust and pulled the wool over everyone's eyes. Not many actually thought Barba was stood down for alcohol and gambling reasons. How does a person in Todd Greenberg's position of trust go forward in his role. It is untenable. He has hidden a potential timebomb from his employers and it has got out. How can that trust stay? He handles himself like no other CEO in front of a microphone but he skirted around the (assault) questions at that press conference. The Daily Telegraph on Tuesday claimed Greenberg did not tell NRL chief executive Dave Smith of the assault allegations at a meeting two weeks after Barba was stood down earlier this season. The NRL's integrity unit is currently investigating the alleged assault. Greenberg was reluctantly forced to answer questions Tuesday when interviewed about the Auckland Nines to be played in February. Fox Sports NRL correspondent Steve Hart has the inside news on the latest chapter in the Ben Barba saga. But he was saying very little. Q: Do you think you will be cleared? A: I'm not going to be making any comments about this issue until after the integrity unit has completed its investigation. Q: Has it been difficult for you? A: I'm not going to comment, no comment. No, nothing. Q: What has Dave Smith said to you? A: I'm not going to comment. Q: Have the headlines been disappointing? A: You are not going to get anything out of me unfortunately. I'm not going to talk about it. Q: We had to ask you Todd. A: I knew you would. Barba was again missing from the Bulldogs team sheet for Thursday night's match against Brisbane. An ankle injury (syndesmosis) has kept the Dally M Medal winner out for another week of NRL. However Canterbury officials are monitoring Barba's injury closely. Barba is telling friends he is close to returning. NSW star Josh Morris will again start from fullback. Prop Sam Kasiano will return from injury off the bench. Meanwhile North Queensland chief executive Peter Jourdain would not debate whether his club was frustrated that halfback Robert Lui was stood down for almost a year for assaulting his partner - while Barba continues to play while his investigation continues. "Each case is different," Jourdain said. I have no idea what happened with Ben Barba. You have to look at all the circumstances before having a view as to what is right or wrong.
